Bones are parts of the skeleton of vertebrates. They also protect organs inside our body.
The bones are the framework of the body. Without them we would be a pile of organs on the ground and would not be able to move.
The skull protects the brain and the ribs protect the heart and lungs. The jaw and
cheekbones support the facial muscles, which help us smile. The rib cage protects the heart and lungs, cranium (skull) protects the brain, pelvis protects the reproductive organs, vertebrae protect the spinal cord. Bones need to be maintained by taking regular exercise and by having calcium from foods like milk, and dark leafy greens such as spinach. The bone marrow in the middle of the bigger bones makes our red blood cells.
