What protein and minerals are human bones and muscles made of?

Human skeleton is mainly composed of collagen, calcium and phosphorus. The interaction of these components forms the hard structure of bones. Bone plays an important physiological function in the human body, including supporting the body, protecting internal organs and producing blood cells.

The muscles of human body are mainly composed of protein such as actin and globin. In addition, muscle also contains many minerals, such as calcium and phosphorus. The interaction of these components makes muscles contract and relax, thus completing various actions and movements.

It is worth noting that although the components of bones and muscles are different, they are very important to the normal physiological function and health of the human body. Therefore, it is very important to maintain adequate nutrition and proper exercise for maintaining the health of bones and muscles.
