| The heart is a muscular organ about the size of a closed fist that functions as the bodyââ¬â¢s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries which provide oxygen and nutrients to body tissues by transporting the blood throughout the body. The heart is located in the thoracic cavity medial to the lungs and posterior to the sternum. |
