Answer:
Explanation:
The inner surface of the small intestine has numerous finger-like projections called villi (Singular villus).
Villi increase the surface area which helps in absorption of the digested food especially fatty acids and glycerol. Also, the blood vessels in that help in absorbing the nutrients into the blood.
