- / 2
- What is the maximal daily colonic fluid absorption capacity?
Answer: 5L
- When does the maximal colonic fluid absorption occur?
Answer: When significant increase in the ileocecal flow is observed
- What does the small intestine secrete?
Answer: HCO3-
- What could cause maximal colonic fluid absorption capacity?
Answer: Could be caused by a decrease in small intestinal absorption and a
compensatory mechanism to prevent an increase in stool water content as in the case of diarrhea
- What does the small intestine not secrete?
Answer: K+
- What does the small intestine absorb?
Answer: Water, Na+, K+ and Cl-
- What is the one thing the colon does not absorb that the small intestine does?
Answer: K+
- What type of secretion is used as a protective mechanism to avoid absorption of
noxious agents or bacteria toxin?
Answer: Epithelial secretion
- What is the correct protective mechanism of epithelial secretion
- Detection of noxious agents or bacterial toxin within the lumen
- Myenteric and submucosal activation (increase intestinal motility and se- cretion)
- Enhance defecation reflex to expel harmful agents
- Follows by water secretion and cause intestinal wall distension
- Increase electrolytes secretion (increase osmotic gradient)
