Which part of the human digestive system is primarily responsible for absorbing most nutrients from digested food?

Explanation

The small intestine is the primary site of nutrient absorption in the human digestive system, with its inner walls lined by tiny finger-like projections called villi that greatly increase surface area for absorbing nutrients into the bloodstream. Digested carbohydrates, proteins, fats, vitamins, and minerals are absorbed here after being broken down earlier in the stomach and small intestine by various digestive enzymes. The small intestine is also considerably longer than the large intestine, further increasing the surface area available for absorption.
