The factor that forces substances to be filtered through the glomerular capillary wall is:
|
|
The osmotic pressure of blood
|
|
|
The hydrostatic pressure of blood
|
|
|
Aldosterone
|
|
|
Renin
|
Explanation:
Detailed explanation-1: -The forces that govern filtration in the glomerular capillaries are the same as any capillary bed. Capillary hydrostatic pressure (Pc) and Bowman’s space oncotic pressure (i) favor filtration into the tubule, and Bowman’s space hydrostatic pressure (Pi) and capillary-oncotic pressure (c) oppose filtration.
Detailed explanation-2: -Within the glomerular capillaries the hydrostatic pressure averages 0.21 kPa.
Detailed explanation-3: -Glomerular filtration depends on the same opposing forces that produce the exchange of fluids in every capillary in our body: these are hydrostatic pressure and oncotic pressure and together they are known as Starling’s forces.
