Question

The factor favoring filtrate formation at the glomerulus is the ____________.

a. colloid osmotic pressure of the blood
b. glomerular hydrostatic pressure
c. capsular hydrostatic pressure
d. myogenic mechanism

Answer 1

Glomerular hydrostatic pressure is the primary force responsible for driving filtration at the glomerulus, overcoming both the colloid osmotic pressure of the blood and the capsular hydrostatic pressure.

Step-by-step explanation:

The factor favoring filtrate formation at the glomerulus is the glomerular hydrostatic pressure. This pressure is the key driving force that pushes water and solutes through the semipermeable filtration membrane in the kidneys. Hydrostatic pressure, in general, is the pressure exerted by a fluid against a surface. In the case of the glomerulus, hydrostatic pressure must override the opposing forces, which include the colloid osmotic pressure of the blood and the capsular hydrostatic pressure. Ultimately, filtration in the kidneys occurs when the glomerular hydrostatic pressure exceeds these opposing forces, resulting in urine formation.

Answer 2

The factor favoring filtrate formation at the glomerulus is the glomerular hydrostatic pressure.

Step-by-step explanation:

glomerular hydrostatic pressure is the pressure of the blood in the glomerular capillaries.

The pressure generated by the fluid against a surface is called the Hydrostatic pressure . The blood in glomerulus generates the glomerular hydrostatic pressure , that forces the fluid out of glomerulus into the glomerular capsule .

Fluid in glomerular capsule generates pressure that pushes the fluid out of glomerular capsule back into the glomerulus , opposing glomerular hydrostatic pressure . this is called the capsular hydrostatic pressure .

The fluid exerts pressure in the opposite direction , and hence , the net movement of the fluid will be in the direction of lower pressure .
