The term for an organ that absorbs nutrients is the "intestine," specifically the small intestine, where most nutrient absorption occurs. The small intestine is elongated and lined with tiny, finger-like projections called villi that increase the surface area for absorption. Once food is digested in the stomach, it passes into the small intestine, where enzymes further break it down, allowing nutrients such as carbohydrates, proteins, fats, vitamins, and minerals to enter the bloodstream. The efficient functioning of the intestine is crucial for overall health, as it ensures the body receives the necessary nutrients for energy and growth.
