Pinyin/Bone

Bones are parts of the human or animal skeleton of vertebrates. They are stiff organs which make up the endoskeleton. Our body is made of flesh and blood built on a framework of bones. Without our bones, we could not stand up or move about. They also protect organs inside our body. The skull protects the brain and the ribs protect the heart and lungs. The teeth support the facial muscles and help us smile. The number of bones in a human's neck is the same as a giraffe's.
