Organs of the Digestive System Several organs make up the digestive system. Every organ has a role in breaking down food and managing waste. Here are the digestive organs in the order in which food travels through them. The digestive tract forms one long tube through the body, all the way ...
The oral cavity, or mouth, is the point of entry of food into the digestive system, illustrated in Figure 1. The food consumed is broken into smaller particles by mastication, the chewing action of the teeth. All mammals have teeth and can chew their food. Figure 1. Digestion of food be...
role in the removal of unused material from the body. The digestive system, also known as the gastrointestinal tract, is made up of the mouth, esophagus, stomach, small intestine, large intestine, rectum and the anus. Read on to find out more about the digestive system parts and functions....

1. 1. The glycopeptide and glycosaminoglycans in the different parts of the digestive tracts of man and rabbit were assayed by determining the carbohydrate content of material which remained after proteolysis. 2. 2. The glycopeptide content was higher in the mucosa than in the muscular-serosa, ...
Gordon and Wostman ('60) show that in the germfree albino rat the absence of the usual intestinal flora modifies the relative weights of the parts of the digestive tract; the weight of the small intestine is reduced while that of the caecum is increased. The length of the small intestine...
What cannot pass through the glomerulus membrane in the kidneys? What are organ systems made up of? What organs are part of the genitourinary system? Which kidney structure empties into the ureter? Are the kidneys a part of the digestive system?

Our digestive system is made up of the organs and structures that allow us to break down the foods we eat into particles that can be used by our cells. The digestive system must break down our foods into their smallest components so that they can be absorbed by our cells. Answer ...
The small intestine is the major site of absorption in the digestive tract. The cells that line the small intestine—gut epithelial cells, or enterocytes— have a cell membrane shaped into fingerlike projections called microvilli, which increases the surface area that each individual cell has ...
