Human skeleton.

The human skeleton is the internal framework of the body, composed of bones that support and protect the organs and tissues. It consists of 206 bones in adults, which are connected by joints and held together by ligaments and tendons. The skeleton provides structure and shape to the body, allows for movement, and serves as a storage site for minerals such as calcium and phosphorus. It also plays a crucial role in producing blood cells and protecting vital organs such as the brain, heart, and lungs.
