NBME 6 Q


The following pulmonary pressures (in mm Hg) were measured in an animal who was breathing spontaneously:

Hydrostatic Capillary Pressure ----- (12)
Oncotic Capillary Pressure --------- (20)
Hydrostatic Interstitial pressure --- (-5)
Oncotic Interstitial Pressure -------- (15)

The Filtration Coefficient of pulmonary microvasculature is 1 ml/min/100 g/tissue / mmHg, and reflection coefficient of proteins is 1. Which of the following best represent the magnitude and direction of fluid flux in this animal?

......Magnitude(ml/mine) ............ Direction

A-...... 2 ............................. Capillary to interstitial space
B-...... 2 .............................. Interstitial space to capillary
C-...... 12 ............................ Interstitial space to capillary
D-...... 12 ............................ Capillary to interstitial space
E-....... 22 ............................ Capillary to interstitial space
F-....... 22 ............................. Interstitial space to capillary

=1*(12-(-5)) - (20-15)= 17-5=12
