What role does the skeletal system primarily serve?

The skeletal system plays a crucial role in providing support to the body's shape and protecting vital organs. It does this by forming a framework that gives the body its structure; without this framework, the body would lack form and stability. The bones of the skeletal system are dense and sturdy, which helps shield organs such as the heart, lungs, and brain from external impacts and injuries. Additionally, the skeletal system serves as a place for muscle attachment, which indirectly supports movement and allows the body to perform various physical activities. However, the primary function remains that of supporting the body and organ protection.

In contrast, the regulation of body temperature is primarily managed by the skin and other systems, not the skeletal system. While the skeletal system does contribute to movement through the attachment of muscles, it is not the primary role. The transportation of nutrients and oxygen is mainly performed by the circulatory system, which includes the heart and blood vessels, rather than the skeletal system itself.
