Question

Draw a neat labeled diagram of intestine villi. [3 MARKS]

Answer 1

Diagram: 3 Marks

The main function of small intestine is absorption. Absorption is directly dependent on surface area. So to increase the surface area, the internal surface of the intestinal wall is folded onto itself creating villi. Again the surface of each villus is convoluted in a similar fashion and the resulting microscopic structures are called as microvilli (brush border).
