Human skeleton

The human skeleton constitutes the rigid framework of the body, providing essential support and maintaining the characteristic shape of the organism. Structurally, it is composed of various bones, which are dynamic tissues constantly undergoing remodeling. Beyond its function of support and protection for soft internal organs, the skeletal system enables movement by serving as attachment points for muscles. Furthermore, it plays a critical role in hematopoiesis, the process of producing blood components within the marrow cavity. The material composition primarily involves calcium phosphate and collagen, which gives the bones their mineral rigidity and tensile strength, respectively.
