Chapter 18, Problem 14RQ
Summary Introduction
To determine:
The net filtration pressure in the capillary considering the existence of following forces: capillary hydrostatic pressure (HPc) = 30 mm Hg, interstitial fluid hydrostatic pressure (HPif) = 0 mm Hg, capillary colloid osmotic pressure (OPc) = 25 mm Hg, and interstitial fluid colloid osmotic pressure (OPif) = 2 mm Hg.

Given the following pressures on the venous end of a capillary, calculate the NET pressure and determine if this pressure is in favor of filtration or reabsorption.
Blood pressure: 15 mmHg
Hydrostatic pressure in the tissues: -3 mmHg
Colloid Osmotic Pressure in a capillary: 28 mmHg
Colloid Osmotic Pressure in tissue: 8 mmHg
Hydrostatic pressure inside the capillary = 34 mmHgColloid osmotic pressure of the blood plasma = 27 mmHgHydrostatic pressure in the interstitial fluid = 2 mmHgColloid osmotic pressure in the interstitial fluid = 4 mmHgWhat is the total pressure favoring filtration?What is the total pressure favoring absorption?What is the net effect of these forces on fluid movement across the wall of the capillary?
Given the following values, calculate the fluid movement between capillaries and tissues:
hydrostatic pressure of the capillary = 25 mm Hg
hydrostatic pressure of the interstitial fluid = 5 mm Hg
colloid osmotic pressure of the capillary = 15 mm Hg
colloid osmotic pressure of the interstitial fluid = 5 mm Hg
Group of answer choices
30 mm Hg into the capillary
30 mm Hg out of the capillary
10 mm Hg into the capillary
10 mm Hg out of the capillary
