Fluid Movement across the Capillary Wall - Part 3
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)   Which of the following forces favor(s) the movement of surrounding interstitial fluid into the capillary lumen (i.e., fluid absorption into the capillary)
(2)   In a typical capillary, the colloid osmotic pressure of plasma is roughly constant throughout the entire length of the capillary.
(3)   In the kidney glomerular capillaries, the colloid osmotic pressure of plasma is roughly constant throughout the entire length of the glomerular capillary.
(4)   Within the kidney glomerular capillaries, the colloid osmotic pressure of plasma __________ as blood moves from the beginning to the end of the glomerular capillary.
(5)   Colloid osmotic pressure of plasma is also referred to as plasma __________ pressure.



(6)   The glomerular filtration rate (GFR) is the rate at which fluid is filtered out of the glomerular capillaries of both kidneys combined to produce the ultrafiltrate that enters the Bowman's space and then the lumen of the nephron. GFR is very high at 125 mL/min. In contrast, the rate at which fluid is filtered out of all other capillaries of the body combined is approximately:
