, Medical Student. The heart, actually, is located in the center of the chest, behind the sternum (or the breastbone). However, a part of it is slightly offset to the left, as you can figure out from the picture above. For understanding this, I think prerequisite knowledge of the heart's basic anatomy is required.
The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes. The heart is located in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria; and lower left and right ventricles.
