GCSE Biology Revision - Heart & Circulation
Settings
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.
