"Digestive Tract"

Along the alimentary canal, there is a smooth lining called the mucosa that assists digestion of food (Burstein, 2009). This is by secreting varied juices, which aid digestion of food along the small intestines, stomach and in the mouth. The main function played by digestive system in human bodies is to break down solid food into tiny particles (Burstein, 2009). This is to enable quick absorption of nutrients through finger like structures called villi found in the capillaries (Lentle & Janssen, 2011). For instance, when one consumes bread and meat, they are not in the right form for the body to absorb its nutrients (Burstein, 2009). Therefore, they ought to change them into smaller molecules to enable effective absorption into the cells, which in turn transmit them throughout the body (Lentle & Janssen, 2011).   2. The Mechanical Aspect of Digestion Mechanical digestion takes place in the mouth whereby saliva, teeth and tongue, play a vital roles in reducing food lumps into manageable sizes (Lentle & Janssen, 2011). Mechanical digestion normally starts in the mouth, which acts as a size reduction unit before other complex processes commences in the body. When one tastes, smells or ingests a loaf of bread in the mouth, salivary glands secrete saliva that softens the bread thus enabling teeth to break it down into smaller pieces. This is by grinding, crushing, slashing and clamping of food to enable it pass smoothly through the esophagus (Burstein, 2009). Swallowing normally encompasses pushing food into the esophagus where it passes through oropharynx and hypopharynx (Lentle & Janssen, 2011). At this point, foodstuff assumes small round forms called bolus and the digestion becomes involuntary (Lentle & Janssen, 2011). A series of muscular contractions called peristalsis transport the food via the rest of the system into the stomach with the aid of sphincter muscle. In the stomach, gastric juices comprises a mixture of hydrochloric acid and pepsin, which break down proteins as well as eliminating harmful bacteria found in the food (Lentle& Janssen, 2011). In addition, strong muscular stomach walls act as a mixer and grinder (Lentle & Janssen, 2011). This is especially during grinding ingested food while enzymes and acids produced by walls digest it chemically (Lentle & Janssen, 2011). A thick liquid called chyne forms in the stomach (Lentle & Janssen, 2011). At this point, the pyloric sphincter valves open allowing chyne to enter into the duodenum where it mixes with acidic enzymes from pancreas and bile from gallbladder.      Once mixing with gallbladder is over, chyme enters into the small intestines where most of the nutrients absorption takes place (Lentle & Janssen, 2011). These nutrients move into the bloodstream and transported into various body tissues. Whatever material is left goes into the large intestine for storage and fermentation (Lentle & Janssen, 2011). Here the colon separates liquid from the waste products until it all solidifies and ready for excretion. 3. The Chemical Aspect of Digestion There are differences evident between chemical and mechanical digestion that takes place in the body of a human being (Lentle & Janssen, 2011). For instance, mechanical process encompasses physical breakdown of large lumps into manageable sizes in the tract system. Mechanical digestion Read More

Crohn's Disease
These two main categories of IBD have very similar symptoms, and definite diagnosis is hard to establish at times, with approximately 10 percent of colitis cases referred as indeterminate colitis, being unable to distinguish which is which. (Crohn's & Colitis Foundation of America) Ulcerative colitis only involves the colon and affects only the superficial layers of its inner lining (mucosa) in a uniform distribution, starting from the anus.

Ulcer can also develop if the epithelial cells known as the goblet cells, in the stomach lining fail to secrete adequate mucus to neutralize the hydrochloric acid in the stomach walls. According to research by Debas p53, some foods taken contains the acids contents which can develop lower PH and become harmful to the stomach.
