Lymphatic System Is a Sub-System of the. Lymphatic system is a sub-system of the circulatory system. It contains a network of nodes, or vessels and filters, which remove toxins from the body. The role of the lymphatic system in the homeostasis of the body is that it serves as the primary drainage for all of the body's other systems, removing all toxins and excess fluids.

It is a major defense against disease and also helps carry nutrients throughout the body. The lymphatic system does not circulate blood. Lymph is its primary fluid and is formed from fluids surround cells throughout the body and passed into lymph vessels. If this fluid were not removed or filtered, the result would be toxins accumulating in the body. This would create swelling and also prevent the body from fighting against infection and disease.

Disorders or complications originated in the lymphatic system create serious illness in the body. This is because this…… [Read More]. Gastroparesis The paper opens with an introduction and definintion of Gastroparesis and its association to damaging of vagus nerves along the intestines and stomach muscles. This reduces their ability for function properly. People living with diabetes have a higher likelihood of advancing Gastroparesis against sequential Diabetic Gastroparesis.

More persons are contracting Gastroparesis during surgical operations. The paper illustrates that more patients are yet to find a cause linking their illnesses with Gastroparesis because it triggers Idiopathic Gastroparesis.

The scope of Gastroparesis has a close link to diseases of connective tissue such as Ehlers-Danlos syndrome as well as scleroderma. The neurological conditions worsen along Parkinson's disease. The paper concludes with proposals of Gastroparesis diagnosis through tests carried out on gastric emptying scans, x-rays, and manometry. Clinical Gastroparesis takes the definition of stomach emptying complications.

The blood in which we are traveling in is composed of red blood cells called hemoglobin, plasma, platelets, and white blood cells. Blood is transported through the body by the heart's pumping action. As we continue, we will enter the hepatic portal vein, which delivers blood from the gastrointestinal tract to the liver, into the ascending aorta, up towards the heart.

As we approach the heart, it's pumping will pull us up into its chambers and through to the lungs where we will get oxygen and continue our journey to the kidneys. As we return to the heart, we will pass through the aortic arch and descend through the thoracic aorta continuing past the descending abdominal aorta until we reach the renal artery. We will make a left turn and pass through the glomeruli through the kidney's tubules and conclude this phase of our journey into the left kidney.

Lipids How Are Lipids Processed. These cells have an enzyme on their surface that attracts fat. The number and distribution of adipose cells has a genetic component, and is usually determined in early childhood. Describe the major metabolic diseases associated with lipid metabolism, transport and storage for humans?

Diseases associated with lipid metabolism, transport and storage included: Saturated fats contain carbon atoms with a single bond between them and as many hydrogen atoms as possible bonded to the carbon atoms. Saturated fats contain carbon atoms with a double bond, and can therefore absorb more hydrogen atoms.

Healthy diets are low in saturated fats, since they raise blood cholesterol levels. There are two essential fatty acids: Phylum Annelida Annelids are members of the Superphylum Lophotrochozoa. The division of the Phylum is in three classes Hirudineans leeches , Oligochaetes earthworms and Hirudinean Polychaetes and leeches. They inhibit marine aquatic with Parapodia, like nereis Meglitsch P, They are worm like animals that have muscular body walls that elongate.

They are also circular in cross section. The major difference between Phylum Annelida and other worm like creatures is that, they have segmented bodies also known as metameric. Each segment has its own particular function.

Phylum Annelida include different types of earthworms, leeches and marine polychaetes. There are those that live in fresh water, marine also terrestrial. Some of them live as parasites.

Additional knowledge is desired to determine if new research findings present clinically significant evidence for use of the intervention in the NICU patient population.

Toward this end, a PICO question has been formulated: Given the increased prominence of theory-based nursing, identifying an applicable nursing framework is important. Indeed, RAM is one of the most common nursing models. Essentially, the model emphasises patient adaptation to the environment Saini et al. Gastrointestinal Tract Disorders of Motility.

For example, in some patients, the stomach is unable to defend itself from the caustic nature of the acid, which creates lesions in the lining, called gastric ulcers. Most patients with GERD suffer from symptoms of other conditions such as Irritable Bowel Syndrome IBS which produces pain, abdominal distress, and the need for frequent bowel movements Gasiorowska ,-page GERD is more prevalent with patients who are over the age of forty although it has been found in patients much younger than this.

Pregnant women or those who have other medical conditions related to the gastrointestinal tract, such as diabetes or hiatal hernia, are more likely to develop GERD.

Age is a major factor as some of the preconditions for GERD such as slower stomach emptying come naturally age. There are three tests which have been traditionally used…… [Read More]. Alcohol the Search for Pleasure. Alcohol is classified as a depressant because it slows down the release of neurochemicals that inhibit certain behaviors. The subjective feelings associated with alcohol intoxication are due to its effects on the brain and central nervous system but that system also controls our behaviors.

The depression of certain neurotransmitters often reduces reflex time and reduces general inhibitions. The digestive system is also strongly affected by alcohol consumption. Alcohol is absorbed almost entirely by the small intestine, from where the alcohol seeps into the blood. The liver is strongly affected by the absorption of alcohol and is in fact the main organ responsible for metabolizing alcohol. Over the long-term, the liver can become permanently damaged from too much alcohol consumption.

The heart and circulatory system are also…… [Read More]. Heart attack education has brought to light the urgency of seeking immediate medical treatment if one suspects they are having heart issues. However, chest pain does not always signal a heart attack, and may be totally unrelated to issues with the cardiovascular system.

Typically, if chest pain is related to a cardiac issue it is usually associated with one of the following symptoms: Scientific Effects of Smoking on the Human. We will give a brief analysis on how smoking affects the mentioned systems and see how the human body system works if the individual does not smoke. We will also support our paper with scientific and statistical evidence regarding the facts related to smoking. Smoking and its effects Before looking at smoking and its effects lets review on how the respiratory and cardiovascular systems work.

The bronchus is spread throughout the lungs like branches on trees and at its tips is as thin as a hair bronchioles. Each lung has about thirty thousand bronchioles. At the tip of every bronchiole lies an area which leads to tiny air sacs known as alveoli. Modality and Public Health Naturopathic medicine is a system for primary healthcare described as a science, an art, philosophy and the practice of diagnosing, treating and preventing illnesses.

This is usually practiced by registered or licensed naturopathic physicians Meadows, Naturopathic medicine is a tradition which is science-based which promotes the wellness of patients through the identification of unique aspects of every patient and then employs natural therapies that are non-toxic in order to restore their psychological, physiological as well as structural balance. Naturopathic medicine is not usually defined by the type of substances that are used rather it is defined by principles which underlie and therefore determine its practice The Healing Arts Center, These principles include; the healing power that exists in nature, finding the cause of illnesses, causing no harm to patients, treating the whole person, prevention of illnesses and doctors acting as teachers to patients.

Health Factors Influencing Support of. It is a well acknowledged truth that memory related diseases like Alzheimer's are common in older people rather than younger ones. Memory tends to becomes less competent with age. It might take longer to learn new things or remember familiar words or names. Many measures can be adopted to reduce the increasing adverse effects of memory like eating a healthy diet, including physical exercise as a part of daily routine and by being social.

Despite of adopting these measures to reduce the effects of growing age on health, these problems cannot be eradicated completely. Young people are more energetic and are less viable to diseases because of the strength of their immune system.

They have a stronger defense system against diseases because of the age. There is a strong relationship between age and support of health. It is tend to occur but applying few important measures cannot…… [Read More]. Diabetes Digestion and Diabetes Overview of the.

Diabetes Digestion and diabetes: Overview of the process The digestive process begins even before food is consumed. Looking at or anticipating food causes salivation. Saliva aids digestion, along with chewing. For example, when Jane Doe looks at a plate consisting of a whole wheat turkey sandwich garnished by vegetables and mayonnaise , potato chips, and apple juice, her body will begin to anticipate eating by secreting digestive juices.

The first major involuntary muscular movement for Jane Doe will not occur until she consciously decides to swallow the food in front of her.

The swallowed food is pushed into the esophagus, the organ that connects the teeth, mouth, and tongue through the throat to the stomach. Taxa What is Cnidaria? What is it made up of? Who are the members that belong to his group? Cnidaria is an exclusively aquatic phylum. It is a group that is represented by the members, who are also called 'polyps', and these are sea anemones and corals, and also by 'medusae', which are creatures like the jellyfish.

In general, both a polypoid as well as a medusoid cnidarian will be either radially or biradially symmetrical and it is an uncephalized animal with one single body opening, which is the mouth. Stinging capsules, which are embedded in the tentacles that are placed around the mouth, generally surrounds the mouth. These stinging capsules are also known as 'nematocysts', and these are capable of acting both as agents of defense as well as of offense. The most important distinguishing feature of a phylum is the presence of the intrinsic nematocysts, and in turn,…… [Read More].

Nutritional Therapies for Ulcerative Colitis. These biologically-based practices of alternative medicine include the use of vitamins, herbs, and food supplements found in nature, chief among which are probiotics: These benign bacteria counteract the presences of the malignant variety, which often cause digestive problems if allowed to overpopulate. Probiotics can be obtained as supplements or found in certain foods, and have been known to prolong periods of remission in ulcerative colitis patients, with no sever side effects.

The use of fish oils is another alternative medicinal treatment for ulcerative colitis. Omega 3 fatty acids are found in certain green vegetables and in nuts, salmon, sardines and herring, as well as in oral supplemental form and are used to treat intestinal inflammation when ulcerative colitis is active. Aloe Vera…… [Read More]. Cow's Milk Got Milk This. Some studies posit that casein consumption has a direct correlation to cancer cell growth, and patients with any form of cancer are counseled not to drink milk, and to limit the consumption of milk products.

This is contradicted in terms of using milk to help with certain stomach and colon cancers Hakkak, Men who drink large amounts of milk and consume numerous dairy products are at a higher risk for Parkinson's disease, and high levels of calcium intake 6 or more glasses of milk per day , also increase the chance for prostate cancer Chen, ; Giovannucci, et.

Additionally, a number of links have been made to digestive disorders such Crohn;'s disease and Hirschprung's disease, which are serious conditions of the digestive system and the bowel "How Bacteria in Cow's Milk…" The idea that the human body requires milk in order to produce calcium and create a stronger…… [Read More].

Animal Nutrition and Feed Evaluation. Agriculture Animal Nutrition and Feed Evaluation Qualitative, scientific-based evaluations of animal feed and the resultant nutrition of the animal are crucial for maintaining optimal animal health and responding to problems that develop as a result of diet. In the case of ruminants, this can be particularly important as their unique digestive system can complicate providing optimal nutrition from traditional feed sources and techniques.

A balanced nutrient approach to ruminant diet must take into account not only the feed that is being given to the animal, but also, crucially, the way in which the animal's digestive system will process that feed and provide or not nutrition to the animal. Creating this type of qualitative knowledge about the digestive system and nutrition needs of rumens with regard to different feeds "developed most rapidly when isotope dilution techniques became easy to apply, facilitated by improved instrumentation and mathematical approaches" 1.

From this information,…… [Read More]. Spina Bifida is one of the many birth defects neonates are at risk of. However, this particular defect is unique because it is characterized by problems in the central nervous system CNS and it has a low death rate.

The causes of this medical condition are quite difficult to determine as they are subject to hereditary and environmental elements. Simply put, Spina Bifida refers to a situation where the spinal cord is not fully developed. In extreme cases, the spinal vertebrae could be so badly formed that the delicate spinal cord is left unprotected. In most cases, the spinal cord suffers damage due to this. The baby could suffer from reduced brain function and poor transmission of commands to affected organs.

This slightly damaged link from the brain to the body tissues and organs leads to poorly developed body systems. There are other associated problems with this spinal defect even…… [Read More]. Epidemiology Liegl-tzwanger, Fletcher and Fletcher pointed out that the exact incidences of gastrointestinal stromal tumors in the United States and Europe is not easy to determine.

This is attributed to the fact that GISTs got proper recognition as well as diagnosis from the late s. Studies carried out in Iceland Tryggvason et al. Incidences if GISTs have been shown to be higher as a result of the fact that most patients live with it for several years and it gets detected only during gastrectomy or autopsy all of which are usually performed for other reasond. Lactose intolerance is a disease aggravated by milk sugars.

It can be controlled by diet, but often other measures must also be used to control the disease, such as the use of dietary aids such as "Lactaid. Lactose intolerance affects millions of Americans. In fact, the American Gastroenterological Association AGA estimates that 50 million Americans suffer from the disease, and it can make their lives miserable if it is not treated. The symptoms of lactose intolerance include stomach cramps, diarrhea, nausea, gas, painful bloating, and flatulence "Living" These symptoms can begin as soon as 30 minutes after consuming…… [Read More].

Military Retirees Are Entitled to. First of all only a scant few of these Veterans groups will acknowledge the "promise" of free health care; for the most part these groups will tout the benefits already promised by the Veterans Administration and assert that cuts in these benefits are the same a broken promise-or contractual breach in legal terms. The idea of the United States military making a "promise" or forging a legally binding agreement between individual veterans or groups of veterans is barred by the United States Constitution.

As will be demonstrated in the Literature eview, specific Constitutional language from Article I give Congress and only Congress the express authority to make laws and regulations pertaining to the armed forces.

Therefore, the idea the military breached a contract with service members is, ultimately, inherently inaccurate. Combining the lack of specific language within the materials provided by any governmental agency with the clear language of the…… [Read More]. Earthworm Dissection Phylum Annelida Is. Earthworms are hermaphrodites since they can generate both sperm and eggs. Mating involves 2 earthworms inseminating each other where sperms are exchanged. The male and female sexual cavities are located near the clitellum.

They connect the lower ends of their anteriors with heads positioned in reverse directions. Mucous secreted joins the openings with slime. Sperm is pushed into the longitudinal channels formed by the mucous.

They reach the sperm receptacles of their partner, which then break apart. Laying of the eggs and fertilization follows "Native Australian," The circulatory system is constituted of the heart, blood and blood vessels. It is needed to distribute nutrition to different areas in the body and is of two types -- open and closed.

One of the immediate responses from Magic Johnson's body with HIV was the weakening of his immune system, which made him -- and makes all HIV-positive patients -- susceptible to the following infections and cancers: Lotus Root There's No Disputing.

Still, others claim that the physical resemblance of Lotus Root to the lungs holds the clue to understanding its healing properties "Health enefits of Lotus Root".

Lotus Root is said to treat various respiratory problems. Small doses of the juice extracted from raw, finely grated Lotus Root is recommended for lung-related ailments such as tuberculosis, asthma, and coughing, for heart disease, and to neutralize toxins.

Lotus Root is also said to be helpful for treating colds because it melts mucus accumulation in the respiratory system. When a Lotus Root plaster is applied to the face, it is believed to relieve sinus congestion and inflammation.

Still, there's no concrete medical authority that backs up the claims that practitioners of Alternative Medicine and Traditional Chinese Medicine make regarding the benefits…… [Read More].

Hydrothermal Vents Life in the. These worms play an integral part of the community. They do not have any digestive capacities, as they lack mouths and digestive systems. They use hemoglobin produced inside their bodies to combine hydrogen sulfide, which is a necessity of many of the bacteria living in and around the vents.

The worms transfer this hydrogen sulfide to the bacteria upon contact, and in return, the absorb the nutrients being produced by the bacteria. Additionally, one study examining vents off the coast of South Africa also found the presence of a new species of nematode, known as Halicephalobus mephisto Borgonie et al. There are also a number of annelids as well as typical crustaceans, like snails, crabs, and shrimp are often common Edmonds et al.

By comparing and contrasting these two popular novels, both describing white men's journey into the space of the Other, the chapter seeks to achieve a two-fold objective: First, they looked into the duration of postoperative ileus if gum was chewed following a cesarean section. Secondly they looked at whether there was a difference in the results when comparing patients who chewed sugar-free gum with the results of those who chewed gum with sugar substitute in it.

In the experiment, 76 women were divided into three categories, the control group, the sugar-free gum group, and the group who were given sugar-substituted gum. The patients who got to chew gum did so every fifteen minutes starting two hours after their surgery. The process is meant to observe normal or pathological conditions of the vessel organization. By seeing the lumen of blood vessels and organs, an angiography can provide information concerning conditions like luminal narrowing and aneurismal widening.

Vessel access is essential and serious complications can appear if the substance is unable to pervade the veins and arteries, but this is rare and unlikely to occur. The discovery of X-rays led to some of the first experiments with angiographies as…… [Read More].

Treating Scleroderma as Chronic Condition. Scleroderma Patient Scleroderma The author of this report has been presented with a hypothetical situation where a forty-four-year-old patient has contracted scleroderma within her lung tissue. There are many implications to having this medical disorder and they are not limited to the medical realm.

Indeed, this report will cover a number of these implications and byproducts including stereotyping by all of society including medical professionals, the overall predisposition for the disease, daily life of scleroderma, comorbidities that might exist or end up happing and social issues such finances, the environment and so forth.

While there are a good number of things that can be done to mitigate, treat or even prevent scleroderma, there are a lot of implications that any scleroderma patient must face and it can be very difficult for the patient.

Meanwhile, the leadership of the NRA -- an organization that indeed does a lot of good, and has millions of responsible hunters as members -- has attacked the science regarding lead poisoning and has taken the position that the law in California calling for non-lead ammunition in condor habitat areas is really an attempt to "ban firearms.

This has always been the NRA mantra when gun safety advocates try to pass legislation: This is a patently absurd but powerful piece of propaganda. I suppose I should report that the process went smoothly and that after a bit of research I now consider myself an expert in regard to the new science of DNA Sequencing. However, I have a thousand more questions now than before I began and even the answers I came up with may or may not be correct.

I do know for a fact that this is a pretty new art or science and its potential seems limitless. Mold Assessment and Indoor Exposure. Certainly, most North Americans spend the majority of our lives indoors, and the quality of our indoor air environment has been shown to play a huge role on our health.

A wide variety of indoor pollutants can have an effect on human health, including environmental tobacco smoke, volatile organic chemicals VOCs and biological pollutants.

Early investigations into sick building syndrome often gave a multi-factorial explanation for the symptoms of occupants. However, these investigations often could not explain the long duration of effects.

Mold Spore Analysis and Toxicity. Mold Spore Trapping Current Scientific Knowledge People are exposed to aeroallergens in a variety of settings, both at home and at work. Fungi are ubiquitous airborne allergens and are important causes of human diseases, especially in the upper and lower respiratory tracts.

These diseases occur in persons of various ages. Airborne spores and other fungi particles are ubiquitous in nonpolar landscapes, especially amongst field crops, and often form the bulk of suspended biogenic debris. The term mold often is used synonymously with the term fungi. A more precise definition would specify that molds lack macroscopic reproductive structures but may produce visible colonies. Respiratory illness in subjects exposed to rust and dark-spored imperfecti fungi was described more than 60 years ago, and physicians worldwide now recognize a sensitization to diverse fungi.

Since fungus particles commonly are derived from wholly microscopic sources, exposure hazards are assessed largely through direct sampling of a…… [Read More]. Nutrition Wheatgrass Is Part of.

The solid waste that passes through the anus is called feces. Other waste would be urine which will pass through the urethra. These are just the basic functions of the digestive system. The path will involve a lot more. To start the digestive path, food will enter the mouth or oral cavity.

Here the teeth will begin to chew the food into smaller pieces. As stated earlier the food is broken down from a solid form to a mushy form and it goes to the pharynx. The pharynx, or better known as the throat, is common passage for food and air to travel. After leaving the pharynx the food then travels through the esophagus to the stomach. The stomachs main purpose is to prepare the food for the small intestine. The food will only leave the stomach when it is chemically ready to.

The process of digesting the food in the stomach will take hours depending on the food consumed. The pyloric sphincter controls when the food will pass on to the small intestine. Rugae, the lining of the stomach, produce an enzyme called pepsin and hydrochloric acid.

These enzymes help to digest food. When leaving the stomach the pyloric sphincter opens and allows the digested food to pass to the small intestine. The small intestine has three parts: The duodenum receives bile from the liver and gall bladder plus food from the stomach. The enzymes and bile breakdown the food more to enter into the jejunum.

The jejunum attaches to the last part of the small intestine called the ileum. There are villi on the lining of the small intestine that will absorb nutrients into lymph vessels and the bloodstream. The large intestine is the last stop in the digestive train is the large intestine. The large intestine has six parts: All of the fluid waste from digestion are received here. The large intestine absorbs water through its walls to make solid feces. After the absorption of the water the defecation process can begin.

The solid feces will leave the body through the anus. Waste that come from the kidneys will leave through the urethra. After all this hard work the process will begin again when food enters the mouth. The process of digestion seems very simple and easy but there are some individuals that have complications with digesting food.

There are several diseases that affect the digestive system. Some common problems are ulcers, hemorrhoids, nausea, anorexia, constipation, and diarrhea. There are other diseases that can lead to very serious problems. A disease called Crohn disease which affects any part of the gastrointestinal tract causes a variety of problems.
