A fingerlike projection of the small intestine that increases the surface area for absorption

Real World Example

Imagine trying to dry a large, wet towel using a small, flat surface area, like a tiny, narrow railing. Just as spreading out the towel over a larger surface allows it to dry more effectively by exposing more of it to air, the small intestine uses villi—tiny, fingerlike projections—to increase its surface area for better nutrient absorption. The connection is clear: just as more surface area helps the towel dry faster, more surface area in the intestines, thanks to villi, allows for more efficient absorption of nutrients into the body.
