All of the Following Enhance the Absorptive Effectiveness of the Small

Question

All of the following enhance the absorptive effectiveness of the small intestine except
A) the circular folds.
B) the villi.
C) the microvilli.
D) intestinal movements.
E) rugae.

Accepted Answer

Rugae are folds found in the stomach lining that allow it to expand; they are not present in the small intestine and therefore do not enhance its absorptive effectiveness. The other options - circular folds, villi, microvilli, and intestinal movements - all contribute to increasing surface area and promoting absorption in the small intestine.
