Question

Why do the villi have many mitochondria

Answer 1

Answer:

The villi and micro villi increase surface area by several orders of magnitude. The second requirement is that the mechanisms for uptake of the various nutrients be fast enough.

Explanation:

Answer 2

Explanation:

I assume you are talking about the cells in our digestive system. One of their primary functions is to take up the end products of digestion from the gut. This becomes much more efficient if the total surface area of cell membrane in contact with the gut contents is large. The villi and microvilli increase surface area by several orders of magnitude. The second requirement is that the mechanisms for uptake of the various nutrients be fast enough. Some require an active transport system that uses ATP and so the cells have large numbers of mitochondria to supply this.

hope it helps!
