The digestive system
Random Fact Large intestine, over the entire lifetime of a person, actually ends up processing around 50 tons of food consumed by an individual. It may be more or less depending on how much a person eats
The Large Intestine Includes the cecum, colon, rectum, and anal canal Larger in diameter, but shorter than small intestine Absorbs water, salts and vitamins Stores indigestible material until elimination
The Cecum Peritonitis – infection of the lining of the abdominal cavity
The Colon Ascending, Transverse, Descending, & Sigmoid Ridding the body of undigested material = maintenance of homeostasis Bacteria break down indigestible material and produce vitamins and molecules
Polyps Growths in the epithelial lining
Diarrhea & Constipation Major causes are infection of the lower intestinal tract and nervous stimulation i.e. food poisoning
