Best Answer

Nutrients are absorbed through the walls of the small intestine into the bloodstream by diffusion or active transport. The structures in the walls of the intestine that allow this to happen are villi, which resemble finger-like projections. They are very well adapted to absorbing nutrients, thanks to a huge surace area, thin cell walls to make diffusion more efficient, and a rich blood supply to keep a strong concentration gradient.

The path that food takes to get out of the small intestine and into the blood is through the body cells. When food is broken down in the stomach, nutrients are absorbed through the intestinal walls. The nutrients cross the mucosa into the bloodstream where they are transported to other parts of the body.
