Question

What structural modification of the small intestine slows the movement of chyme through the lumen? a) intestinal crypts b) villi c) microvilli d) circular folds.

Answer 1

Answer:

The correct answer is d) circular folds.

Explanation:

Circular folds slow food going through the small intestine so the villi and microvilli can help the food to be processed and digested properly. Also, the presence of these circular folds increases the surface where the nutrients are being absorbed.
