Heart

The heart is a muscular organ inside the human body, as well as inside other animals. It is located in the thoracic cavity (the chest) inside the ribcage, positioned a small bit to the right (and in one's point of view, to the left) from the center of the chest between the lungs and above the diaphragm. The human heart, along with the hearts of other mammals and birds, is divided into four chambers: the smaller right and left atria (singular: atrium), and the larger right and left ventricles.

It is known for being the central organ for the circulatory system for its trademark function of pumping blood through the blood vessels, receiving and sending blood throughout the body, but in dyrahumans, the heart also pumps the invisible energy, lutma, which gives dyrathletes their ability to perform extraordinary moves in sports.
