Villi feature microvilli, a rich blood supply, single-layer epithelium, lacteals, intestinal glands, and membrane proteins to maximize absorption.
Villi in the small intestine have features like microvilli (increasing surface area), a rich blood supply, single-layer epithelium, lacteals, intestinal glands, and membrane proteins to facilitate absorption.
