Bones are primarily known for their role in providing structure and support, but they are also essential for protection. The skeletal system, which consists of 206 bones in the adult human body, protects vital organs. For instance, the skull encases the brain, the ribcage shields the heart and lungs, and the vertebrae protect the spinal cord. These protective roles are a result of the unique histological structure of bones, which combines strength and some degree of flexibility.
