c. Absorption of protein occurs primarily in the small intestine
d. Increase acidity of stomach contents

Answer 1

Villi and microvilli are structures in the small intestine that increase the surface area for absorption.

Step-by-step explanation:

Villi and microvilli are structures in the small intestine that increase the surface area for absorption. Villi are folds in the surface of the small intestine, while microvilli are cytoplasmic extensions on individual cells. These structures play a key role in the absorption of nutrients from the digested food and their transfer into the bloodstream.
