The fluids leave the capillaries at the arterial end because...
the net filtration pressure of the blood is higher at the arterial end than it is at the venous end.
the net filtration pressure of the blood is higher at the venous end than it is at the arterial end.
the net filtration pressure of the interstitial fluid is higher at the arterial end than it is at the venous end.
the net filtration pressure of the interstitial fluid is higher at the venous end than it is at the arterial end.
the osmotic pressure is higher at the arterial end than it is at the venous end.
