also just 2 make it in2 a more exam styled answer

left ventricle is thicker because it needs 2 'withstand the high pressure'

[UberCuba]

@EkLarkiThi no, dont say that. You would need to say that the left ventricle is thicker because it has to produce enough pressure to pump the blood around the whole body, not to withstand pressure. You would say that arteries have thicker walls than veins to withstand the high pressure.
