Detailed explanation-1: -The lining of the small intestinal mucosa is very highly specialized for maximizing digestion and absorption of nutrients. The lining is highly folded to form microscopic finger-like projections called villi which increase the surface area to help with absorption.
Detailed explanation-2: -The epithelial cell are covered by smaller projections like villi known as microvilli which increases the absorption capacity of the intestine. The microvilli is covered with digestive enzymes that help in breaking down carbohydrates and proteins. In this way villi helps in absorption of food.
Detailed explanation-3: -Final answer: Villi increases the surface area for absorption in intestines.
Detailed explanation-4: -Villi and microvilli enhance the small intestine’s surface area, which improves nutrient absorption by diffusion. The small intestine’s villi and microvilli, which make up the inner layer of epithelial tissue, aid in the absorption of nutrients from chyme.
Detailed explanation-5: -The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions.
