When the circulatory system works it helps you stay alive.Did you know that you really have two pumps in the heart? The pumps are called the pulmonic valve, and the other is called Tricuspid. One is for pumping blood into the heart, and the other for pumping blood to the rest of the body.

Your heart has lots of things it’s made of. It is made of the Pulmonic valve, libercated skin, Aorta, Right Atrium, Left Atrium, Coronary Arteries, Triecuspid vavle, Right Ventricle, Left Ventricle, Pericardicim, and Tissues. They work inside the heart.

Did you know, if you didn’t have a heart you would die? This is because your heart pumps blood into the rest of your body. Every time you breath you take in oxygen, and it goes up through your body. You need oxygen to breath. Oxygen goes into your blood stream and is taken to all the cells of your body.

Did you know that every one has about twenty five trillion blood cells? That’s more blood cells then there are stars in the Milky Way Galaxy!

Every time you breathe you take in oxygen. But did you know that your heart and lungs work together? This is because the heart and lungs connect to each other. The heart pushes the air into the lungs. But for breathing your lungs do most of the work, and for blood the heart does most of the work. The heart pumps these twenty five trillion blood cells into the rest of the body.
