Which of the following is a feature of the small intestine which increases the surface area to maximise the diffusion rate during absorption of food molecules? * 1 point
-Rich blood supply
-Wall of the villi is only one cell thick
-The villi contain lacteals
-The walls of the small intestine contain villi

The walls of the small intestine contain villi

Explanation:

In order to increase the rate of absorption, the walls of the small intestines have membrane projectiles known as Villi. By protruding from the intestinal walls, Villi are able to absorb more than if the walls were just a flat surface.

The Villi are then made up of microvilli to increase their surface area as well. The Villi contain capillaries that will transport the nutrients they absorb such as glucose to other organs such as the liver.
