Food that has been fully digested in the small intestine is in liquid form. How does this food leave the intestine?
Study how the inner part of the intestine looks.
The inner surface of the intestine i s larger than its outer surface because it has any folds. These folds have fingerlike “bumps” called villi. The villi which contain blood vessels absorb or take in the digested food. As blood travels inside the body, it carries the food to the cells. The cells then absorb the food to become part of the body.
