Quizplus · Accepted Answer

The majority of nutrient absorption takes place in the small intestine. This is due to the large surface area of the small intestine, which is lined with finger-like projections called villi and microvilli that increase surface area even further. Nutrients from food are absorbed into the bloodstream through the walls of the small intestine and transported to the rest of the body. The stomach is primarily responsible for breaking down food with acid and enzymes, while the pancreas secretes enzymes to aid in digestion in the small intestine. The large intestine mainly absorbs water and electrolytes, but only a small amount of nutrients.
