What is the main function of the skeletal system?

The main function of the skeletal system is to provide support, protection, and facilitate movement. The skeletal system is composed of bones and cartilage, which create a framework for the body. This framework supports the weight of the body, allowing for upright posture and stability.

Protection is another critical function; bones encase and protect vital organs such as the skull safeguarding the brain and the ribcage protecting the heart and lungs. Furthermore, the skeletal system works closely with muscles to allow for movement. When muscles contract, they pull on the bones, enabling a wide range of physical activities, from walking to complex movements like playing sports.

Additionally, the skeletal system is involved in the production of blood cells through the bone marrow within certain bones, contributing to the overall health and function of the body.
