When the contents of stomach are sufficiently processed, they are released into the small intestine. It is made up of threee segments - the duodenum, jejunum, and ileum. Small intestine is a 22-foot long muscular tube that breaksdown food using enzymes released by the pancreas and bile from the liver. The duodenum is largely responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream. It is a 6-foot long muscular tube that connects the small intestine to the rectum. Its function is to absorb water fromthe matter, and then to pass uselesswaste material from the body The Mouth is the beginning of the digestive tract; and, in fact, digestive starts here when taking the first bite of food. Located in the throat, near trachea, the esophagus receives food from your mouth when you swallow.Through the series of muscular contractions called peristalsis, the esophagus delivers food to your stomach. LIVER The liver has multiple functions, but its main function within the digestive system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting fat. In addition, the liver is the bodys chemical "factory." It takes the raw materials absorbed by the intestine and makes all the various chemicals the body needs to function. The liver also detoxifies potentially harmful chemicals. It breaks down and secretes many drugs. PANSCREAS The pancreas secretes digestive enzymes into the duodenum, the first segment of the small intestine. These enzymes break down protein, fats, and carbohydrates. The pancreas also makes insulin, secreting it directly into the bloodstream. GALL BLADDER The gallbladder stores and concentrates bile, and then releases it into the duodenum to help absorb and digest fats. ANUS The anus is the last part of the digestive tract. It is a 2-inch long canal consisting of the pelvic floor muscles and the two anal sphinctersIt lets you know whether the contents are liquid, gas, or solid. The anus is surrounded by sphincter muscles that are important in allowing control of stool.
