The interacts with the in such a way that the skeletal system takes its calcium and phosphorus supply from the digestive system.

The skeletal system cannot produce its own calcium to strengthen itself. It depends on the digestive system. When a person eats food that contains calcium and phosphorus, the body breaks the food down into smaller molecules that can be absorbed by the body into the bloodstream. With the aid of the , the smaller molecules of calcium and phosphorus are then delivered into the bone tissues that need them for repair and to strengthen themselves.
