Villi present in the inner lining of intestinal wall
Answers
Answer:
The digested food is taken up by the walls of the intestine. The inner lining of the small intestine contains numerous finger like projections called villi. The villi increase the surface area for absorption. Each villus is covered by a single layer of epithelium and contains blood vessels and lymph vessel.
Answer:
Villi present in the inner lining of intestinal wall the surface area available for absorption.
Explanation:
Numerous folds of mucous membrane known as plicae circulares cover the inside of the small intestine. The villi and microvilli on the surface of these folds further expand the surface area available for absorption.
Villi, which resemble fingers, are many finger-like projections that line the interior of the small intestine. The absorbing surface area is increased by the villi. Blood and lymphatic tubes can be found inside each villus, which is coated in a single layer of epithelium. Through the epithelium, the meal diffuses into the blood vessels.
Simple columnar epithelial tissue lines the small intestine's inner wall, often known as the mucosa. Amino acids, carbohydrates, and lacteals are transported into these capillaries by the villi's epithelial cells from the intestine's lumen (lipids).
