Given the following forces acting at a given point across the capillary wall, what type of fluid movement will be taking place at that point
Capillary blood pressure = 32 mmHg
Plasma-colloid osmotic pressure = 23 mmHg
Interstitial fluid hydrostatic pressure = 1 mmHg
Interstitial fluid-colloid osmotic pressure = 0 mmHg
A)Ultrafiltration will occur with a net outward pressure of 8 mmHg.
B)Ultrafiltration will occur with a net outward pressure of 10 mmHg.
C)Ultrafiltration will occur with a net outward pressure of 56 mmHg.
D)Reabsorption will occur with a net inward pressure of 24 mmHg.

Ultrafiltration will occur with a net outward pressure of 8 mmHg. This is calculated by taking the capillary blood pressure (32 mmHg) and interstitial fluid hydrostatic pressure (1 mmHg), which together exert an outward force, and subtracting the inward forces exerted by the plasma-colloid osmotic pressure (23 mmHg) and the interstitial fluid-colloid osmotic pressure (0 mmHg), resulting in a net outward pressure of 10 mmHg - 2 mmHg = 8 mmHg.
