Question

Give three reasons why the Villi in the small intestine are perfect for absorbing food?​

Answer 1

Answer:

The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions. The surface of these folds contains tiny projections called villi and microvilli, which further increase the total area for absorption.

Answer 2

Answer:

Three reasons for Villi in the small intestine are perfect for absorbing food are:-

i) Villi are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path.

ii) They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.

iii) Villi increase the internal surface area of the intestinal walls making available a greater surface area for absorption.
