Question
Chapter 18.5, Problem 6QC
Summary Introduction
To review:
The overall net filtration pressure in capillary, and whether it is the net absorption or the net filtration that takes place in the capillary.
Introduction:
The colloid osmotic pressure gradient is created due to different concentrations of solutes in the blood and the capillary. The colloid osmotic pressure draws the water inside the capillary because less solute is present in the interstitial fluid and more solute is present in the blood. The hydrostatic pressure moves the water out of the capillary because the hydrostatic pressure inside the capillary is more as compared to the hydrostatic pressure inside the interstitial fluid.

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?
What four variables determine the net filtration pressure across the capillary wall? Give representative values for each of them at the arteriolar and venous ends of a systemic capillary.
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
