    Does anyone have any tips on how to remember what the Arteries, Capillaries and Veins do? What size each one is? What they do? and the pressure that they are?

    Tbh I'd just try and memorise them - it's not that much and you have time!

    Arteries - blood away from the lungs, oxygenated, high (?) blood pressure, large, thick muscular walls
    Veins - blood towards lungs, deoxygenated, lower blood pressure, smaller, thinner walls, valves to prevent backflow due to gravity
    Capillaires - blood transfer withing tissues, oxygen and CO2 diffuse through one cell thick walls into other cells, very small (only just wide enough for a red blood cell)

    Good Luck with the rest of your exams too. I have now finished all of my exams and I am doing pre A2 work at college. (I was retaking my GCSE Biology at college because I wanted to do Environmental Studies at AS Level)
