Quizplus · Accepted Answer

All of the options listed enhance the absorptive effectiveness of the small intestine.

-The plicae circulares are circular folds in the intestinal lining that increase the surface area for absorption.
-The villi are finger-like projections on the lining of the small intestine that contain blood vessels and lymphatic vessels to help absorb nutrients.
-The microvilli are tiny, hair-like projections on the surface of the epithelial cells that line the villi, which further increase surface area for absorption.
-Intestinal movements, such as peristalsis, help mix and propel intestinal contents, which enhances contact with the absorptive surface of the small intestine.
