The digestion process is a series of reactions of food with the digestive hormones and juices. It has been found that another proteinase, rennin, is present in the stomach of infants. Food can be digested by a combination of two methods mechanical digestion and chemical digestion, Food is initially broken down in the mouth by the grinding action of teeth (chewing or mastication), The tongue pushes the food towards the back of the throat, where it travels down the esophagus as a bolus, The epiglottis prevents the bolus from entering the trachea, while the uvula prevents the bolus from entering the nasal cavity, The stomach lining contains muscles which physically squeeze and mix the food with strong digestive juices ('churning), Food is digested within the stomach for several hours and is turned into a creamy paste called chyme, Eventually the chyme enters the small intestine (duodenum) where absorption will occur, Peristalsis is the principal mechanism of movement in the oesophagus, although it also occurs in both the stomach and gut, Food is moved unidirectionally along the alimentary canal in a caudal direction (mouth to anus), Segmentation involves the contraction and relaxation of non-adjacent segments of, Segmentation contractions move chyme in both directions, allowing for a greater mixing of food with digestive juices, While segmentation helps to physically digest food particles, its bidirectional propulsion of chyme can slow overall movement. If a person has diarrhea, they should pay special attention to hydration as they lose more water than normal through diarrhea. The colon is responsible for absorbing water from the lumen, so the stool can form. Which process do the bacteria in the gut use to digest lactose?

Digestion in the body occurs chemically and mechanically. Chemical digestion actually starts in the mouth when our saliva mixes in with the food. This is why defecation is usually done once a day. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. These chemicals are used by cells as energy sources. Mechanical digestion of all foods begins in the oral cavity. Lastly, the large intestine packages and pushes the remaining undigested and indigestible food out of the body through the anus; it eliminates the waste. If the damage is mostly in the small intestines, it is called Crohns Disease; if it is only in the large intestine, it is called Ulcerative Colitis (UC). Why? That may seem kind of gross to discover that your gut is home to more bacteria than there are cells in your body, but most of these bacteria are harmless, and some are even beneficial.
