Heart Diagram

Your heart is a very strong muscle that works non-stop.  It pumps blood around your body.  The blood carries oxygen and food to keep your body working.  Your heart is so strong that it only takes a minute to pump blood to your toes and back again!

  • The right side of your heart sends blood to the lungs to get oxygen.
  • Blood returning from the lungs is full of oxygen.
  • The left side of your heart pumps this blood to all parts of the body.
  • Oxygen makes blood a bright red colour.
  • The blood in your arteries contains more oxygen than the blood in your veins.
  • Tiny blood vessels called capillaries take the blood from the arteries to all the cells of the body.
  • Other capillaries then take the blood back to the veins.

Blood is made up of red blood cells, white blood cells and platelets in a liquid called plasma.

Red blood cells carry oxygen around the body.

White blood cells fight germs.
