Atria

Deontoxynated blood
Blood that comes from other parts of the body that has less oxygen, and more carbon dioxide. It must go to the lungs to get more oxygen.
Healthy heart
A balanced diet, exercise and rest are very important for a healthy heart.
Pulse investigation
Plan, Design, carry out and write up an investigation to examine the effect of exercise on pulse rate. You may use the timer on your iPad as a stopwatch.
Consider how you will measure the pulse.
Do you need a control?
How will you ensure accuracy?
How long does it take for the pulse to go back to normal resting rate? What does this show?
