Fluid Movement across the Capillary Wall - Part 2

Movement of fluid across the capillary wall is governed by hydrostatic pressure differences as well as osmotic pressure differences across the capillary wall. Test your basic knowledge of this process by taking this simple quiz.

(1) When considering the forces that govern fluid movement across the capillary wall, which of the following is/are correct?

	(A) A positive net filtration pressure refers to a condition that favors the movement of fluid out of the capillary lumen and into the surrounding interstitial fluid (i.e., fluid filtration out of the capillary).
	(B) A negative net filtration pressure refers to a condition that favors the movement of fluid out of the capillary lumen and into the surrounding interstitial fluid (i.e., fluid filtration out of the capillary).
	(C) A positive net filtration pressure refers to a condition that favors the movement of surrounding interstitial fluid into the capillary lumen (i.e., fluid absorption into the capillary).
	(D) A negative net filtration pressure refers to a condition that favors the movement of surrounding interstitial fluid into the capillary lumen (i.e., fluid absorption into the capillary).

(2) Which of the following is/are among the forces that govern fluid movement across the capillary wall?

	(A) Hydrostatic blood pressure in the capillary
	(B) Colloid osmotic pressure of the interstitial fluid surrounding the capillary
	(C) Hydrostatic pressure of the interstitial fluid surrounding the capillary
	(D) Colloid osmotic pressure of plasma

(3) In a typical capillary, the net filtration pressure is positive throughout the entire length of the capillary.

	True
	False

(4) In the kidney glomerular capillaries, the net filtration pressure is positive throughout the entire length of the glomerular capillary.

	True
	False

(5) Which of the following forces favor(s) fluid movement out of the capillary lumen and into the surrounding interstitial fluid (i.e., fluid filtration out of the capillary)?

	(A) Hydrostatic blood pressure in the capillary
	(B) Colloid osmotic pressure of the interstitial fluid surrounding the capillary
	(C) Hydrostatic pressure of the interstitial fluid surrounding the capillary
	(D) Colloid osmotic pressure of plasma
