Can someone please give me notes or something, cause all i have as notes is the revision guide and a huge textbook :( and my exams are in three weeks!!
In my text book it says the main reason is that it mainly re-enters the capillaries by the loss of hydro static pressure within them, so by the time the blood gets to the venous end of the capillary the hydrostatic pressure is less within the capillary than outside them in the tissue fluid, so the tissue fluid is forced back into the blood in the capillary. However when i look at mark schemes it says that it mainly re-enters by osmosis? How does it move in by osmosis? ( i know that the remaining moves back into the bloodstream via the lymphatic system)
