Question

what is the role of hydrostatic pressure in capillary exchange?
has no effect on capillary exchange
causes blood clotting in capillaries
pushes fluids out of the capillaries
decreases the flow rate of blood in capillaries
pulls fluids into the capillaries

Explanation:

Hydrostatic pressure is the force exerted by a fluid at rest. In capillary exchange, blood hydrostatic pressure (BHP) is the pressure of blood pushing against the wall of a capillary. It is the primary force driving fluid out of the capillaries and into the interstitial fluid. For example, at the arterial end of a capillary bed, BHP (around 35 mmHg) is higher than interstitial fluid hydrostatic pressure (IFHP, close to 0 mmHg), so fluid is pushed out.

Answer:

Pushes fluids out of the capillaries
