Question

what is the role of Villi in human digestive system

Answer 1

There are also enzymes (enterocyte digestive enzyme) on the surface for digestion. Villus capillaries collect amino acids and simple sugars taken up by the villi into the blood stream. ... They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.

Answer 2

Answer:

Villi are finger-shaped projections located in the small intestine and helps in absorption of nutrients.

Explanation:

• Villi are finger-shaped projections located on the surface of the small intestines directed towards the lumen of the intestine.
• They are responsible for increasing the surface area of the intestine so that the nutrients produced after the digestion of the food can be effectively absorbed and transferred throughout the body.
• The villi possess lymphatic ducts called the lacteal duct which is responsible for the uptake of lipid and fat molecules from the small intestine.
