What is one of the functions of the skeletal system?

The skeletal system plays a crucial role in protecting internal organs, which is one of its primary functions. The bones provide a sturdy framework for the body and serve as a protective barrier for vital organs. For example, the skull encases and protects the brain, while the ribcage safeguards the heart and lungs from external injury.

Additionally, the vertebral column, or spine, encases the spinal cord, which is essential for transmitting nerve signals between the brain and the rest of the body. This protective function is vital for maintaining overall health and safety, as it prevents damage to these sensitive structures. Thus, the ability of the skeletal system to shield internal organs underscores its importance in the human body.

The other choices—production of heat, storage of nutrients, and regulation of blood pressure—are functions associated more with other body systems such as the muscular system or the endocrine system, rather than being primary functions of the skeletal system.
