Did you know that the heart is the hardest working muscle in your body? Its job is to pump blood throughout your entire body, and it does this over 100,000 times each day! Imagine the heart as a house. It has four rooms, or chambers. The two chambers on top are called atria, and the two on the bottom are ventricles. The heart pumps blood from the atria to the ventricles, and then out to the rest of the body. This pumping of blood is very important because it carries oxygen and nutrients to every single cell in your body. Without the heart, our cells wouldn't get these vital elements to keep us healthy and alive! Keeping our heart healthy is crucial. Eating a balanced diet full of fruits, vegetables, whole grains, and lean proteins can help keep our heart strong. Also, regular exercise helps our heart because, like all muscles, the more we use it, the stronger it gets. So, let's appreciate our super pump and take care of it. Can you think of any other ways to keep our hearts healthy?
