What primary function does the skeletal system serve for vital organs?

The primary function of the skeletal system in relation to vital organs is protection. The skeletal system includes bones that form a protective framework around critical organs. For instance, the skull encases the brain, safeguarding it from injury, while the rib cage shields the heart and lungs from physical trauma. This protective role is essential for maintaining the integrity and functionality of these organs, ensuring that they remain safe from external forces that could cause harm.

The other choices address different roles of the skeletal system. For example, supporting functions emphasize how bones provide structure to the body, while storage refers to the role of bones in storing minerals and fat. These aspects are important but do not encompass the primary protective function that the skeletal system serves for vital organs.
