Nutrients diffuse through the small intestine's walls into the blood stream so that the blood can carry them to the cells in the body.
Why Is Diffusion Important In Digestion?
Digestion is a complex process that starts with eating. Chewing and enzymes in saliva start to break down food even before it is swallowed. Stomach acid kills any potentially dangerous bugs and lowers the pH so that digestive enzymes that break down proteins can get to work.
When the food leaves the stomach and enters the small intestine, other digestive enzymes break all food components ~ proteins, carbohydrates and fats into small molecules that can be absorbed. The small molecules pass through the cells of the intestine and enter the blood.
Some of this movement takes place by a process called diffusion. Diffusion is the movement of a substance, down its concentration gradient from a region of high concentration to a region of low concentration. Some of the food molecules diffuse across the cell membrane of the intestinal cells and into the cytoplasm. They then cross the cell and leave to enter the blood. This movement can occur by diffusion but the cell can also control movement of many substances using active transport.

In chemistry, Biology: The mixing of two or more substances and movement from higher concentration towards lower concentration is known as diffusion. Diffusion breaksdown the food which we eat in to small pieces. It is important part of digestion because the bigger peices cannot digest by the stomach so diffusion makes them in to smaller.
