Is the heart behind the left lung or in the center?
Someone please prove my friend wrong!!
It's just slightly to the left of the midline.
The center of the chest
In between the lungs
It is dead center. The left ventricle pumps the hardest though so it is best heard slightly to the left. The left ventricle has to pump blood throughout the body... that's why it pumps hardest.... but it sits in the middle of your chest,
