The primary function of the small intestine is to absorb nutrients from the food we eat. It accomplishes this by receiving partially digested food from the stomach and breaking it down further with enzymes produced by the pancreas and liver. As the food passes through the small intestine, nutrients are absorbed into the bloodstream and transported to the rest of the body for energy and growth. The small intestine also plays a role in the immune system by preventing harmful bacteria and toxins from entering the body.
