Question

what purpose does the highly folded surface of the small intestine serve? multiple choice increases the intestinal motility facilitates efficient absorption of nutrients traps pathogenic bacteria increases flexibility of the gi tract

Explanation:

The highly folded surface of the small intestine (with villi and microvilli) increases the surface area. A larger surface area allows for more efficient contact between nutrients in the digested food and the absorptive cells, thus facilitating efficient absorption of nutrients. Intestinal motility is related to muscle contractions, not folding. Trapping bacteria is not the role of the folded surface, and flexibility of the GI tract is not related to this folding for absorption.

Answer:

B. Facilitates efficient absorption of nutrients
