what pressure is responsible for reabsorption and for pulling fluids into the venous end of capillaries?
At the venous end of the capillary, net osmotic pressure exceeds hydrostatic pressure. by 8 (25 minus 17) mmHg. This can be described either as a net filtration pressure of. -8 mmHg, or as a net absorption pressure of +8 mmHg. Either way, there is a. tendency for fluid to re-enter the capillary at its venous end. This amounts to a net. reabsorption rate of 12 ml/min across all capillary beds. It will be evident that net filtration at the arterial end and net reabsorption at the. venous end of the capillary do not quite balance.
