What you will learn
Explain that the heart pumps blood carrying oxygen to the muscles, that heart rate and breathing rise with exercise because muscles need more oxygen, and measure a pulse.
How to play
- Choose what the body is doing: sleep, sit, walk, run or sprint.
- Watch the heart beat, the lungs breathe and the blood flow round the body.
- Switch on control and set the heart rate yourself. Can you keep the muscles supplied?
- Finish three challenges, including counting your own pulse (it stays on your device).
