can someone explain the topic of tissue fluid?

At the venule end, the water potential is lower in the venule that the tissue fluid, so plasma moves into the venule.
Hope this helps

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

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.
Hope this helps

So I think I got a Low B in unit 1
And an A in my empa
Do you think it's possible to still get an overall A if I try to get an A in unit 2?
Thanks
