Document Summary

Comprised of the alimentary canal (gi tract) and accessory organs. Food in lumen of gi tract is outside body because the gi tract is continuous withoutside world alimentary. Accessory organs mouth, pharynx, esophagus, stomach, small intestine, colon teeth, tongue, gallbladder, salivary glands, liver, pancreas. Absorbs digested material through lining into blood. Produce saliva, bile, enzymes (things that aid in digestion) most digestive organs in the abdominopelvic cavity; slick, friction reducing serous membranes. Mesentery: fused double layer of parietal peritoneum carry blood vessels, lymphatic vessels, nerves. also stores fat and supports intestinal organs. Visceral peritoneum: covers external surfaces of digestive organs, continuous with parietal peritoneum. Parietal peritoneum: lines walls of abdominopelvic cavity. Peritoneal cavity: slitlike potential space between visceral and. Serous membrane is made up of simple squamous epithelium. Most of the pancreas and some of the colon are retroperitoneal. Peritonitis: piercing abdominal wound, perforating ulcer, burst.
