READ IT! LEER

The center of your circulatory system is your heart. It has a big job to do because it pumps blood to every cell in your body. Your heart never stop beating.

The heart pumps blood to your lungs first to get oxygen. Then it pumps this oxygen , rich blood all over your body. Blood moves away from your heart through arteries. This blood is bright red because it contains oxygen.

After your blood gives oxygen to the cell in your body, ir picks up carbon dioxide and other wastes than your cells make.

Then blood will move back to your heart through your veins. The blood in your veins is darker because it doesn´t carry any oxygen.
