The Small Intestine: Where Food Digestion Primarily Occurs

Most of the breakdown of your food takes place in your small intestine. The small intestine is a long, narrow tube that connects your stomach to your large intestine. It is lined with villi, which are small, finger-like projections that increase the surface area of the intestine and help to absorb nutrients from food. The small intestine also contains enzymes that break down carbohydrates, proteins, and fats into smaller molecules that can be absorbed into the bloodstream.
