The system of bones in the human body is called the skeletal system. It consists of 206 bones in adults, providing structure, support, and protection for vital organs. The skeletal system facilitates movement by serving as attachment points for muscles. Additionally, it plays a crucial role in producing blood cells, as bone marrow is responsible for hematopoiesis, the formation of red and white blood cells. The skeletal system also acts as a reservoir for minerals, such as calcium and phosphorus, which are essential for various bodily functions. Overall, it is vital for maintaining overall health and stability.
