The heart is a vital organ located in the center of the chest with a slight tilt to the left. Using rhythmic muscle contractions, it circulates blood through veins and arteries, which supplies tissues with oxygenated blood and disposes waste.
Where is your heart located in the chest? On average, a human heart weighs 10.5 ounces; it's around the size of a clenched fist and is cone shaped. The human heart is made of cardiac muscle, which contracts the heart and regulates the heart beat.
