Fluid Exchange Across the Walls of Capillaries

View the animation below, then complete the quiz to test your knowledge of the concept.

1.		The fluids leave the capillaries at the arterial end because...
			A)	the net filtration pressure of the blood is higher at the arterial end than it is at the venous end.
			B)	the net filtration pressure of the blood is higher at the venous end than it is at the arterial end.
			C)	the net filtration pressure of the interstitial fluid is higher at the arterial end than it is at the venous end.
			D)	the net filtration pressure of the interstitial fluid is higher at the venous end than it is at the arterial end.
			E)	the osmotic pressure is higher at the arterial end than it is at the venous end.
2.		The fluids reenter the capillaries at the venous end because...
			A)	the net filtration pressure of the blood is higher at the arterial end than it is at the venous end.
			B)	the net filtration pressure of the blood is higher at the venous end than it is at the arterial end.
			C)	the net filtration pressure of the interstitial fluid is higher at the arterial end than it is at the venous end.
			D)	the net filtration pressure of the interstitial fluid is higher at the venous end than it is at the arterial end.
			E)	the osmotic pressure is higher at the venous end than it is at the arterial end.
3.		Approximately what percent of fluid that exits the capillaries at the arterial end renters the capillaries at the venous end?
			A)	60%
			B)	70%
			C)	80%
			D)	90%
			E)	100%
4.		The lymphatic capillaries reabsorb as much as 20% of the fluid lost by the blood capillaries.
			A)	True
			B)	False
5.		The net osmotic pressure is equal at both the arterial and the venous ends of the capillary.
			A)	True
			B)	False
