Which of the following is a primary role of the skeletal system?

The primary role of the skeletal system is to protect internal organs. The skeleton serves as a structural framework for the body and provides protection for vital organs. For instance, the rib cage shields the heart and lungs, while the skull encases the brain. This protective function is essential for overall health and safety, allowing the organs to function without the risk of injury from external forces.

While other systems such as the endocrine system are responsible for hormone production, the digestive system manages food processing, and the nervous system handles impulse conduction, these functions are not tasks of the skeletal system. Thus, the protective role of the skeletal system is crucial in maintaining the integrity and function of the body.
