|
Filtration dominates at the venous end of a capillary bed, and is driven by osmotic pressure.

|
|
Filtration dominates at the venous end of a capillary bed, and is driven by hydrostatic pressure.

Explanation:
Detailed explanation-1: -Filtration dominates at the venous end of a capillary bed, and is driven by hydrostatic pressure. Filtration dominates at the arterial end of a capillary bed, and is driven by hydrostatic pressure. net hydrostatic pressure minus the net colloid osmotic pressure. be higher than normal.
Detailed explanation-2: -Because of the gradient of the hydrostatic pressure along the capillary, filtration usually occurs at the arterial end of the capillary and reabsorption at its venous end.
Detailed explanation-3: -The hydrostatic pressure of the blood is much higher at the arterial end of the capillary, thus favoring filtration.
