Question
State three adaptations of the villi in the absorption of food.
Solution
-
Increased Surface Area: The villi are small, finger-like projections that protrude from the lining of the small intestine. This greatly increases the surface area for absorption, allowing more nutrients to be taken in at a time.
-
Presence of Microvilli: Each villus is covered with even smaller projections called microvilli. These further increase the surface area for absorption and also contain enzymes that aid in the breakdown of nutrients.
-
Rich Blood Supply: The villi contain a network of capillaries. These blood vessels allow for the quick absorption of nutrients into the bloodstream. Once in the blood, the nutrients can be transported to cells throughout the body.

Villi are small structures that contain tiny blood vessels. Villi have very thin walls. Small nutrient particles can cross the villi's thin walls and move into the blood vessels. These particles are then carried in the blood throughout the body.Which part of the digestive system has villi?The small intestine.
