Document Summary

Mouth -> pharynx -> esophagus -> stomach (2-6 hours) -> small intestine (3-10 hours) -> large intestine (up to 72 hours) -> rectum -> anus. 2 organ groups: alimentary canal (digest/absorb food) From ventral body cavity in mouth -> rectum: accessory organs (mechanical/chemical digestion) Vitamin k, b & biotin: neurotransmitter & hormone production (gastrin, ghrelin, cholecystokinin, secretin, vip, motilin, gastric inhibitory peptide & neuro acetylcholine, serotonin, histamine, nitric oxide) Peritoneum: visceral peritoneum (external surface of digestive organs, parietal peritoneum (lines body wall) Route for blood vessels, lymphatics & nerves. Holds organs in place (stabilize so can"t become entangled in digestive movement) Elastic fibres allow stomach to regain shape after eating: muscularis externa. Retroperitoneal organs have adventitia and serosa (facing peritoneal cavity & against. Fibrous adventitia in esophagus replaces it dorsal body wall) Stem/ paneth cells (produce antimicrobial molecules: lamina propria. Major intrinsic nerve plexuses: submucosal nerve plexus. Regulate glands & smooth muscle in mucosa: myenteric nerve plexus.
