Anatomical terminology [edit on Wikidata]

Bones are parts of the skeleton of vertebrates. They also protect organs inside our body.^[1]

The bones are the framework of the body. Without them we would be a pile of organs and skin on the ground and would not be able to move.

Bones also protect us. The skull protects the brain and the ribs protect the heart and lungs. The jaw and skull support the facial muscles, which help us eat and move our mouth. The pelvis protects the reproductive organs, and vertebrae protect the spinal cord.

Bone is living tissue, and must 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.
