What is the second most important function in skeletal system?

Storage of minerals

The skeletal system is a mineral reservoir, storing 99% of the body's calcium and 85% of its phosphorus. These minerals are essential for bone strength and rigidity. They are also involved in a variety of other bodily functions, such as muscle contraction, nerve conduction, and blood clotting.

When the body needs calcium or phosphorus, it can draw upon the stores in the bones. This process is called bone resorption. Bone resorption is balanced by bone formation, so that the overall mass of the skeleton remains constant.

The storage of minerals in the skeletal system is important for maintaining bone health and overall body health.
