Digestive system

Gastroparesis is a digestive system disorder; gastroparesis affects the stomach muscles. This disorder causes weakening of the stomach muscles, this causes poor churning and mixing of food by the stomach contractions and the normal movement of the stomach muscles that propel the food forward through the digestive tract is slowed down or in some cases they completely stop working. This prevents the food form being emptied from the stomach. Diet changes can be used to treat this condition.…

Crohn’s disease (CD) is a chronic inflammatory bowel disease (IBD) characterized by inflammation of the digestive or gastrointestinal tract. Crohn’s can affect any part of the gastrointestinal tract from the mouth to the anus, but is more commonly found at the end of the small intestine where it joins the beginning of the large intestine (or colon). It can also affect an individual’s eyes, skin, and joints. Interestingly, the incidence and prevalence of Crohn’s disease is high in industrialized…

The gastrointestinal system is the system that is used to break down food and absorb nutrients that are essential for the bodies’ survival. In the gastrointestinal system, there is a special mechanism for motility and breakdown of nutrients. This system is facilitated by four types of tissue; muscosa, submucosa, muscularis externa and serosa (Sherwood, 2010, p.591-594). The muscosa is innermost layer that serves multiple functions with an epithelial layer for protection and portions for…

macronutrient. The digestive system of worms and enzymes involved in nutrient breakdown Worms digestive system is highly specialized, the first step of digestion starts at the Worm's mouth. Once the worm opens it mouth, concurrently the pharynx opens up aswell. As the food travels down the pharynx the food goes down into the esophagus which…

Every time we eat the body functions to digest the food we are consuming. One of the organs of the digestive system is the liver which is placed in the right upper quadrant of the abdomen and plays a major role in the intermediary metabolism as it breaks down the fat, it produces bile acids and it is the key organ for detoxification. Liver diseases nowadays seem to be very common; especially in the Western world, it is estimated that 1 in every 10 adults suffers from a condition called…

Introduction A gastrointestinal arteriovenous malformation is a rare defect of tangled veins and arteries involving the intestine. This defect can occur anywhere in the intestine. The defect creates an abnormal collection of blood vessels that can put pressure on other parts of your body that are close by. It causes blood vessels to expand (dilate) over time and sometimes bleed. Many people with this defect never have any symptoms. This defect is present at birth (congenital). What are the…

All mammals digest food through a similar system- even if there are specializations that have developed over time in adaptation for the diet of each animal. Each kind of animal uses the mouth opening, and often teeth, to acquire the food regardless of what stage—live, raw, cooked, etc.—and introduce it to the digestive tract. Almost all animals have a small and large intestine, wherein the separation and absorption of nutrients occurs. At the end of the small intestine the caecum is found in…

Colon cancer is a type of cancer that attacks the large intestine walls or the lower part of your digestive system. Colon cancer usually attacks in the sides or in the innermost layer part of the large intestine and then it starts to grow. At first colon cancer is detected; small and then it progressively get bigger and bigger. One of the worst things about colon cancer is that you can not really detect it because there are no symptoms whatsoever, if colon cancer symptoms are detected it is…

Introduction The gastrointestinal system (digestive system) is the alimentary tract from the mouth to the anus with its associated glands and organs (Moore, 2016) It originates from two germ layers, the endoderm and mesoderm, and receives nerve supply by cells derived from the third germ layer, the ectoderm(van den Brink, 2007) (McLin et al., 2009) The earliest stage of development is the ‘primordial gut’ which forms during the 4th week as the head, tail (caudal eminence) and lateral folds.…
