Blood delivers at the ____________ end of a capillary bed and picks up at the ____________ end of a capillary bed. this is because the pressures in and out are close to balancing. if hydrostatic pressure is ____________ mm hg at the arteriolar end and the colloidal osmotic pressure is ____________ mm hg. this means more pressure forcing fluid out of the capillary. at the venular end the hydrostatic pressure is ____________ mm hg and the colloidal osmotic pressure is still the same, so fluid returns to the capillary.
