Which organ is responsible for breaking down food sufficiently to allow nutrient absorption?

The small intestine is crucial for breaking down food so that nutrients can be absorbed into the bloodstream. After food is partially digested in the stomach, it moves to the small intestine, where enzymes from the pancreas and bile from the liver further digest food into its nutrient components. The walls of the small intestine are lined with villi, microscopic finger-like projections that increase the surface area for absorption, allowing nutrients to pass through into the bloodstream efficiently. This organ plays a significant role in digesting carbohydrates, proteins, and fats, ensuring that the body gets the essential nutrients it needs for energy, growth, and repair.
