The transport of nutrients from the gastrointestinal tract into the body is called absorption. This process occurs primarily in the small intestine, where digested nutrients pass through the intestinal walls and enter the bloodstream or lymphatic system for distribution to cells and tissues. Efficient absorption is crucial for providing the body with essential vitamins, minerals, carbohydrates, proteins, and fats necessary for overall health.
