Which bone is the breastbone?

Explanation:
The breastbone is the sternum, a flat bone located along the midline of the chest that forms the front part of the rib cage. It protects the heart and lungs and serves as the central anchor for the ribs via costal cartilage, plus it connects with the clavicles at the sternoclavicular joints. The sternum consists of the manubrium at the top, the body in the middle, and the xiphoid process at the bottom. The other bones mentioned are not the breastbone: the ilium is part of the pelvis, the scaphoid is a bone in the wrist, and the clavicle is the collarbone that sits above the rib cage and connects to the sternum but is not the breastbone itself.
