Stickmen's guide to
YOUR BEATING HEART
Your Beating Heart reveals how oxygen from your lungs is carried round your body by the blood, pumped by the heart, and taken to the cells – every single one of them. This nonstop activity involves trillions of red blood cells and a vast network of arteries, veins and capillaries. You’ll find out what the blood is made of, what happens when you exercise, and see how a heart transplant works. Oh, and if your brain is deprived of oxygen for even a few minutes, it will be damaged – so it’s as well no one has to remember to breathe!
