Answer 2

$\huge\mathfrak\red{ ANSWER}$

Intestinal villi are a unique structural and functional unit for the luminal sensing, digestion, absorption, secretion, and immune defense in the small intestine.

Villi are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.
