Document Summary
Chyme will pass through jejunum then go to ileum. Most of it lies in upper left quadrant. Absorbs remainder of nutrients from chyme, as well as fat and water. Starts wide at duodenum then narrows o as it approaches ileum. In right lower quadrant, remaining 3/5 of the small intestine. Jejunum and ileum: held together by mesentery and blood is fed using superior mesenteric artery. Absorbs remaining water, nutrients, and fat from chyme through chemical digestion before chyme moves into large intestine through the ileocecal valve into the cecum. Entering into large intestine, chyme passes through ileocecal valve. Parts of large intestine: cecum, vermiform appendix, ascending, transverse, descending and sigmoid colon, rectum and anus. Teniae coli: smooth band running along ascending colon, transverse colon and descending colon. They are thickened bands of smooth muscle that allow for food to be passed through haustra. Allow for contraction of muscles to allow movement of food.
