Learning time​

Kids learn by watching short, engaging video lessons.

The circulatory system is very important. It is made up of the heart, blood, and the blood vessels. The purpose of this system is to deliver oxygen and nutrient-rich blood to all the cells in the body and carry away waste such as carbon dioxide that your body produces. The heart is the size of a fist and is located in the left-hand side of the chest. Blood from the body is carried into the right atrium. This blood is full of carbon dioxide. The blood then moves into the right ventricle, and this is squeezed to the lungs. In the lungs, the blood picks up oxygen and releases carbon dioxide. The oxygen-rich blood then enters the left atrium, then the left ventricle where it is pumped to the rest of the body.
