When you eat, your body digests the food so your cells can use it to make energy.
Acids and enzymes eat away at the surface of food to break it down.
The small intestine is where food is broken down into molecules tiny enough for the body cells to use.
In the villi are tiny tubes that carry blood called VESSELS. Food molecules are taken into these blood vessels. Once the food is in the blood, it can travel all over the body.
