what is a villi?
Solution
Villi are small, finger-like projections that extend into the lumen of the small intestine. They are part of the intestinal lining (the mucosa). Each villus is approximately 0.5-1.6 mm in length and their function is to increase the surface area of the intestine, which enhances the absorption of nutrients during digestion. Each villus is covered with epithelial cells and has a network of capillaries and fine lymphatic vessels called lacteals close to its surface, which aid in the absorption and transport of nutrients.
