The heart is located in the chest behind which bone?

Explanation:
The heart sits directly behind the sternum in the chest. The sternum forms the front boundary of the thoracic cavity, so the heart lies posterior to it within the mediastinum. The spine is behind the heart, the diaphragm is below, and the clavicles are above and to the sides, not directly in front of the heart. This front-to-back relationship is why chest compressions are aimed at the sternum.
