Question

multiple choice question
the villi and microvilli greatly increase the ______ of the small intestine, which allows for faster absorption of nutrients into the bloodstream.
muscular peristalsis
surface area
volume
ph

Explanation:

Villi and microvilli are finger - like projections in the small intestine. They increase the area available for nutrient absorption, which is the surface area. Muscular peristalsis is related to movement of food, volume doesn't directly relate to absorption rate in this context, and pH is about acidity or alkalinity and not what is increased by villi/microvilli.

Answer:

B. surface area
