How does the hydrostatic pressure change from the arterial end of a capillary to the venous end of a capillary? Do you see similar changes in colloid osmotic pressure?
Blood pressure at the arterial end of capillaries is about 40 mm Hg in humans. If blood pressure at the venous end is about 15 mm Hg, and colloid osmotic pressure is 25 mm Hg throughout, what is the net effect on fluid movement between capillaries and tissue spaces?
What is the only solute that has a significant concentration difference across the capillary wall? How does this difference influence water concentration?
