In a healthy human, the net filtration pressure for glomerular filtration is
Solution:
The net filtration pressure (NFP) is the effective pressure that causes filtration of blood in the glomerulus. It is calculated by considering the opposing pressures:
NFP = Glomerular Hydrostatic Pressure (GHP) - [Blood Colloidal Osmotic Pressure (BCOP) + Capsular Hydrostatic Pressure (CHP)]
Typical values in a healthy human are:
-
Glomerular Hydrostatic Pressure (GHP) = 55 mmHg
-
Blood Colloidal Osmotic Pressure (BCOP) = 30 mmHg
-
Capsular Hydrostatic Pressure (CHP) = 15 mmHg
Therefore, NFP = 55 mmHg - (30 mmHg + 15 mmHg) = 55 mmHg - 45 mmHg = 10 mmHg.
Thus, the net filtration pressure for glomerular filtration in a healthy human is 10 mmHg.
