What is one of the main functions of bone?

One of the main functions of bone is to provide body support and protect vital organs. The skeletal system forms a framework that supports the body, allowing for an upright posture and the ability to move. Additionally, bones encase and safeguard critical organs; for example, the ribcage protects the heart and lungs, while the skull protects the brain. This functional aspect of bones is essential for overall health and stability, contributing to movement and physical activity.

While other options mention important biological functions—such as nutrient absorption or nerve cell formation—these do not accurately reflect the primary roles of bone tissue within the human body. Bones primarily serve as structural supports and protective barriers, making body support and organ protection the correct choice.
