    The heart is typically the size of a fist: 12 cm (5 in) in length, 8 cm (3.5 in) wide, and 6 cm (2.5 in) in thickness.

    How big is the heart? This depends. Are you a human? Well, then it is generally about the size of your fist. This is not really very big when you think about the job it does. In some animals, such as horses, the heart size to body size ratio is much greater. This helps explain why horses are such great endurance athletes! The heart is also bigger in champion endurance athletes, due to genetics and training. In a sense, the heart is really two hearts, the left heart and the right. Both sides pump the same amount of blood, but to different locations at different pressures. The right side (right ventricle) pumps oxygen-depleted blood that has returned from the body to the lungs for reoxygenation. This is a short trip and requires little pressure development, so the right ventricle is rather thin walled like a fireplace bellows. The left side (left ventricle) is the real workhorse, pumping oxygenated blood that has returned from the lungs (the right and left side of the heart are thus connected) to the entire body. The left heart muscle is thicker as a result, just as your bicep would become thicker if you had to lift heavy weights with it all day.
