The heart is a powerful organ that pumps blood throughout our body. Thanks to the heart, blood is delivered to all tissues; cells receive oxygen (the gas that enables the body to produce energy) and nutrients (substances obtained from food necessary for the body). Waste products are also removed from the body. The heart also helps maintain the body’s temperature (the heat that enables energy production and healthy functioning).Pumping BloodThe heart muscles continuously contract and relax to cir
