Where is my heart located exactly? The heart itself is only the size of a fist, and itâs exact location is behind the breastbone (sternum) and slightly to the left of center, as you can see in the diagram above. So if you are looking down at your body, place your hand right in the center of your chest.
The heart is a hollow, muscular organ located between the lungs and underneath the breastbone. A muscular wall divides the heart into two sides â the right side and the left side. Each side has two chambers. The two upper chambers of the heart are called the atria. The atria are the filling chambers.
