Detailed explanation-1: -Bones support your body and allow you to move. They protect your brain, heart, and other organs from injury. Bone is a living, growing tissue. It is made mostly of two materials: collagen (KOL-uh-juhn), a protein that provides a soft framework, and calcium (KAL-see-uhm), a mineral that adds strength and hardness.
Detailed explanation-2: -Bones also protect internal organs from injury by covering or surrounding them. Your ribs protect your lungs and heart, the bones of your vertebral column (spine) protect your spinal cord, and the bones of your cranium (skull) protect your brain (Figure 10.1.
Detailed explanation-3: -Protection of vital organs, e.g. heart and lungs (protected by rib cage), brain (protected by the skull) (Note: not all vital organs are protected by bones, e.g., the intestines.)
