Question
Chapter 18, Problem 13CYU
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 OPif 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.

Blood pressure at the arterial end of capillaries is about 40 mm Hg in humans. If blood pressure at the venous end is about 15 mm Hg, and colloid osmotic pressure is 25 mm Hg throughout, what is the net effect on fluid movement between capillaries and tissue spaces?
Describe what Bulk flow across a capillar bed. A. In your description, define what Net filtration pressure is, hydrostatic pressure, and colloid osmotic pressure. B. What should occur at the arterial end of the capillary bed and what should occur at the venous end of the capillary bed? ( in other words, tell me if fluid should be moving out capillary or should be moving into 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
