Measurement of the functions of a nephron reveals a glomerular capillary pressure of 69 mm Hg, and apressure in the capsular space of 15 mm Hg. Assuming that the colloid osmotic pressure is 30 mm Hg, and thatessentially no plasma proteins are filtered by the glomerulus, what is the net filtration pressure in this case?A)69 mm HgB)84 mm HgC)24 mm HgD)30 mm HgE)99 mm Hg

Respuesta :

Answer:

Option C

Explanation:

Given -

Pressure in the glomerular capillary [tex]= 69[/tex] mm Hg

Pressure in the capsular space [tex]= 15[/tex] mm Hg

The colloid osmotic pressure  [tex]= 30[/tex] mm Hg

Also no  plasma proteins are filtered by the glomerulus

In this scenario -

Net filtartion pressure is equal to

Pressure in the glomerular capillary [tex]-[/tex] Pressure in the capsular space [tex]-[/tex]colloid osmotic pressure

Substituting the given values in above equation, we get -

[tex]69 -15 -30\\[/tex]

[tex]= 24[/tex]  mm Hg

Option C is correct
