What is the primary function of the skeletal system?

The primary function of the skeletal system is to provide protection for internal organs. The bones create a sturdy framework that safeguards vital organs, such as the brain (protected by the skull), the heart and lungs (protected by the rib cage), and the spinal cord (protected by the vertebral column). This protective role is crucial as it helps prevent injury and damage to these organs from external forces.

While the skeletal system does indeed contribute to movement by serving as attachment points for muscles, this is not its primary function. The production of heat is primarily managed by muscle tissue, and the transport of nutrients is mainly carried out by the circulatory system. Thus, the key role of the skeletal system in protecting internal structures highlights its essential function in maintaining overall bodily integrity and health.
