The primary function of the digestive system encompasses both digestion and the reabsorption of nutrients. Digestion refers to the process of breaking down food into smaller components that can be easily absorbed by the body. This includes mechanical and chemical processes that occur in the mouth, stomach, and intestines.

Once food is digested, the digestive system is responsible for reabsorbing the essential nutrients, vitamins, and minerals from the digested food into the bloodstream, where they are then delivered to cells throughout the body for energy, growth, and repair. This nutrient absorption primarily takes place in the small intestine.

By integrating these two functions—digestion and the reabsorption of nutrients—the digestive system ensures that not only is food broken down efficiently, but that the body receives the nourishment it requires to function properly. The answer captures the comprehensive nature of the digestive system's role in maintaining overall health.
