Question

Calculate the net filtration pressure in the capillary:

Plasma oncotic pressure = 26 mmHg
Plasma hydrostatic pressure = 35 mmHg
Interstitial oncotic pressure = 3 mmHg
Interstitial hydrostatic pressure = 0 mmHg
a) 4 mmHg
b) 11 mmHg
c) 31 mmHg
d) 58 mmHg

Answer 1

The net filtration pressure (NFP) in capillaries, which is calculated using hydrostatic and oncotic pressures, is 12 mmHg when using the provided values; however, this does not match the options given, indicating a potential typo in the provided choices.

Step-by-step explanation:

The net filtration pressure (NFP) in capillaries is calculated by considering both hydrostatic pressure and oncotic (osmotic) pressure. The formula for NFP is NFP = (Plasma hydrostatic pressure + Interstitial oncotic pressure) - (Plasma oncotic pressure + Interstitial hydrostatic pressure). Using the values provided:

NFP = (35 mmHg + 3 mmHg) - (26 mmHg + 0 mmHg) = 38 mmHg - 26 mmHg = 12 mmHg.

It appears there might be a typo in the provided options, as 12 mmHg is not listed, however, it is the correctly calculated Net Filtration Pressure with the given values.
