The heart is tasked with pumping blood where it pumps oxygenated blood to the body and deoxygenated blood to the lungs. The heart also has three main types of blood vessels that ensure the blood is transferred throughout the body. This test covers the B3 unit of AQA GCSE Biology on heart and circulation. Give it a try and see just how ready you are for the exams.

Recovery takes longer
Resting heart rate gets faster
Lungs grow much larger
Resting heart muscles contract harder
More water is needed for sweating
More oxygen is needed by muscle cells
Warmer muscles work faster
Active muscles need more lactic acid
