At the arteriole end, there is a high hydrostatic pressure, forcing plasma out of the capillaries. The RBCs, WBCs and platelets remain in the capillary because they are too large. This results in a more negative water potential in the capillary. At the venule end, the water potential is lower in the venule that the tissue fluid, so plasma moves into the venule.
Before you say anything, no I'm not sponsored by this guy or anything, but if you search Mr Pollock biology on youtube, there's a good playlist for unit 2, with most of the topics covered

Does anyone know of/have any exam style questions that aren't past papers? Or maybe some international papers? I'm struggling with the application but can only really find the past papers from aqa
can someone give a detailed description/explanation of crossing over and independent assortment
dont need to know it in detail for aqa, all you need to know is that for crossing over, chromatids of different chromosomes will wrap around eachother, snap off and exchange alleles. Independent assortment is literally just that they line up in random orders each time the cell goes through metaphase, however it only really affects the genetic diversity during meiosis really.
