Heart Diagrams
These drawings show how your blood comes into the right side of your heart from the main veins in your body and gets pumped into your lungs. The blood then takes on oxygen from the lungs and is sent to your head and the rest of your body.
The blood flowing into the right side of your heart is short on oxygen and carries waste products(eg.carbon dioxide). When it gets to the lungs it dumps the carbon dioxide and takes on fresh oxygen.
Rich in oxygen now, your blood circulates to all parts of your body through your arteries. These are the channels that take your blood from the left side of your heart to the tissues in your body. They branch all the time and get smaller until your blood reaches the tiny capillaries.
Heart Diagrams and Circulation
Your blood now releases the oxygen and nutrients and collects waste products from your cells. It continues to flow through the veins and soon gets back to the right side of your heart. Then it does it all again.
