@doctor.asky: How the body absorbs nutrients from food. In the small intestine, digestive enzymes turn carbohydrates into simple sugars, proteins into amino acids, and fats into fatty acids. The inner lining of the intestine is covered with millions of tiny finger like projections called villi. These greatly increase surface area, allowing more nutrients to pass through. Inside each villus are small blood vessels and a lymph channel that carry nutrients away.
