Explanation:
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: -One of the main functions of villi is to absorb nutrients from the lumen in the small intestine. Since the walls of the villi are only one cell thick, the nutrients are able to quickly pass from the villi into the blood. They do this using a process called diffusion.
