The Digestive System consists of the Alimentary Canal and various other organs whose primary function is to support the Digestive System.
The Alimentary Canal, is a long tube about 10 meters long which starts at the mouth and ends at the anus. This tube consists of multiple sections which each have their own specific functions to perform in the process of digestion. The sections of the Alimentary Canal in the order in which they process food are
the function of the lingual papillae are
The alimentary tract serves primarily to convert food into absorbable particles and to pass them on to the other organs of the body. These events are initiated by mechanical processes (fragmentation, mixing, transport) and the secretion of digestive juices containing enzymes, which act to split proteins, fats and carbohydrates by hydrolysis into constituents small enough to be absorbed (digestion). These end products of digestion, together with water, minerals and vitamins, then pass through the intestinal mucosa, from the lumen of the intestine into the blood and lymph (absorption).
