How are villi suited/ adapted to their function?

Answer:

-Have lacteal; for absorption and transportation of fatty acids and glycerol;
-Have network of capillaries/highly vascularized; to transport absorbed food substances;
-Have thin epithelium; to reduce the distance travelled by materials hence faster diffusion of digested food substances;
-Have microvilli; to increase the surface area for absorption of nutrients;
-Have numerous mitochondria; to provide energy for active transport of nutrients;
