Question
Chapter 18.10, Problem 17CYU
Summary Introduction
To review:
The answers to the following:
a. To predict the flow of fluid if a severe bacterial infection occurs in the surrounding tissue.
b. To calculate the NFP at the venous end of the capillary if OP increases to 10 mm Hg.
c. The direction of fluid flow at the venous end.
Introduction:
Blood flow is also known as tissue perfusion. It is involved in transporting nutrients and oxygen to the tissues, exchanging of gases, absorbing nutrients, and producing urine. The flow of blood to all the organs is maintained for their proper function.

Suppose OP if rises dramatically—say because of a severe bacterial infection in the surrounding tissue. (a) Predict how fluid flow will change in this situation. (b) Now calculate the NFP at the venous end of the capillary. If OP if increases to 10 mm Hg. (c) In which direction does fluid flow at the venous end of the capillary now—in or out?* (see fig. and attached with snipped method if neccessary)
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?
Assume the following pressures on the arterial end of a capillary:
Plasma hydrostatic pressure = 35mmHg
Plasma osmotic pressure = 26mmHg
Interstitial hydrostatic pressure = 0mmHg
Interstitial osmotic pressure = 1mmHg
Given the pressures listed above, what is happening to fluid in this scenario?
A. Fluid is leaving the capillary
B. Fluid is entering the capillary
C. Fluid is leaving the cell
D. Fluid is entering the cell
