What are Villi or Define Villi?
Villi are finger-like projections of the small intestine that increase the surface area for absorption of nutrients. Each villus has a network of capillaries and lymph vessels that absorb the nutrients from the food. Villus – Definition Structure Role and FAQs.

Structure of Villi
A villus (plural villi) is a small, finger-like projection that extends from the surface of an organ or tissue. Villi are found in the small intestine and are covered in tiny, hair-like projections called microvilli. The surface of a villus is covered in small blood vessels that absorb nutrients from digested food.
Villi Diagram
The villi diagram is a visual representation of the intestinal villi. The diagram shows the location of the villi along the length of the intestine, and the size and shape of the villi. The diagram also shows the blood vessels that run through the villi, and the digestive enzymes that are released by the villi.
Role of Villi in the absorption of food
Villi are tiny, finger-like projections that line the small intestine and increase the surface area for the absorption of food. The villi are covered in tiny, hair-like projections called microvilli, which increase the surface area even more. The villi and microvilli are covered in small blood vessels that absorb the nutrients from the food.
Absorption of Nutrients and Elimination of Waste:
The process of absorption of nutrients and elimination of waste begins with the ingestion of food. The food is broken down into small pieces in the stomach and then passes into the small intestine, where the nutrients are absorbed into the bloodstream. The waste products are eliminated through the rectum and anus. Villus – Definition Structure Role and FAQs.
