Document Summary

Teniae coli: 3 bands of longitudinal smooth muscle in muscularis. Haustra: sacs pouches formed to the wall of the large intestine by contraction of teniae coli. Rectum: three rectal valves stop feces when releasing gas farting. Anal canal: last segment of the large intestine. Lots of deep crypts with goblet cells for mucus production. Haustral churning moves content from haustra to haustra. Gastrocolic reflex: used when food enters stomach, 3-4 strong waves per day in the colon: digestion. Bacteria ferment digest even further than enzyme, digest cho (cellulose, lactose, -saccharides) Bacteria convert remaining proteins into amino acids indole, skatole, fatty acid, hydrogen sulfide. Bacteria decompose bilirubin to simpler pigments (stercobilin) grey feces instead of white. Bacteria produces some vitamin b, k: absorption. Remaining water reabsorption, and other absorptions including vitamin k, electrolytes, short chain fatty acid: defecation. Feces- unwanted waste including water, inorganic salts, undigested food, bacteria products etc. Mass movements with gastrocolic reflex to move feces into rectum.
