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.
In humans, the heart is a fist-sized muscle located slightly to the left of center in the chest. It acts as an engine for the circulatory system, pumping blood through the blood vessels. It will beat approximately three billion times in an average human lifespan.
