Gcse triple science biologyWatch
The spec is absolutely massive so sadly I've got no idea what's going to come up :/ If it does I reckon you'll either have to:
Describe the function of one or two pieces (1-2 marks)
Describe the route blood takes through the body. (~4 marks)
Your call if you'd like to spend 15-20 minutes of last minute revision time on it. Good luck!
i'm assuming you're talking about the aqa exam. if so, the spec says that 'students should know the structure and functioning of the human heart and lungs.'
the parts that we need to know are listed as the 'lungs, heart, right/left ventricle blood vessels, aorta, vena cava, pulmonary artery, pulmonary vein and coronary arteries.'
'knowledge of the names of the heart valves is not required.'
(in any case, labelling the heart just might be better than a 6-mark written question on how the heart and blood vessels are adapted for oxygen transportation.)
