The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system. The right atrium receives blood from the veins and pumps it to the right ventricle.
The heart is a mostly hollow, muscular organ composed of cardiac muscles and connective tissue that acts as a pump to distribute blood throughout the bodyâs tissues. The heart is the epicenter of the circulatory system, which supplies the body with oxygen and other important nutrients needed to sustain life.
