Answer: 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.
