How does the concept of surface area most relate to the absorption of nutrients?

Question

Quizplus · Accepted Answer

The large numbers of villi and microvilli in the small intestine increase the surface area available for nutrient absorption. This is because the villi and microvilli have a finger-like shape which protrudes from the intestinal wall, increasing the surface area available for contact between the nutrients and the absorptive cells. This means that nutrients can be absorbed much more efficiently than if the intestinal wall was simply flat.
