Question

question 2 of 10
when is hydrostatic pressure greater than osmotic pressure?
hydrostatic pressure is never greater than osmotic pressure.
at the venular end of the capillaries.
at the arterial end of the capillaries.
at the midpoint of the capillaries.

Explanation:

Hydrostatic pressure is the force exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semi - permeable membrane. At the arterial end of the capillaries, blood pressure (hydrostatic pressure) is relatively high and is greater than the osmotic pressure, causing fluid to move out of the capillaries into the interstitial space.

Answer:

C. At the arterial end of the capillaries
