What is the primary function of the skeletal system?

The primary function of the skeletal system is to provide structure and support to the body. The skeleton acts as a framework that gives shape to the body and supports the weight of various organs and tissues. It serves as an anchor for muscles, enabling movement when muscles contract and pull on bones. Additionally, the skeletal system protects vital organs, such as the brain, heart, and lungs, by providing a hard, protective casing. While the skeleton is involved in producing blood cells through the bone marrow and plays a role in other functions such as mineral storage, its fundamental role is to offer support and shape to the body.
