Question

The three pressures responsible for glomerular filtration​

Answer 1

Answer:

The process by which glomerular filtration occurs is called renal ultrafiltration. The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron.

Answer 2

A N S W E R :

The different pressure responsible for the process of glomerular filtration are –

• Glomerular Hydrostatic Pressure (GHP) = 60 mm Hg.

• Blood Colloidal Osmotic Pressure (BCOP) = 32 mm Hg.

• Capsular Hydrostatic Pressure (CHP) = 18 mm Hg.

E X T R A I N F O R M A T I O N :

• Glomerular filtration takes place in the Renal corpuscles (Malpighian corpuscles) of the " Uriniferous tubule ".

• In glomerular filtration, pressure is used to filter the aqueous medium and small solute molecules.

• Water passes through the basement of the Bowman's capsule.

• Glomerular filtration takes place through the three barriers that constitute the filtration membranes.

• The three barriers that constitute the filtration mambrane are – (i) Fenestrated endothelium of the capillary (ii) Basement membrane (iii) Filtration sites.

• As the diameter of the efferent arteriole is larger than that of the afferent arteriole, there is a resistance towards the flow of blood in the Glomeruli.

• If the diameter of the afferent renal arteriole is decreased, and that of the efferent renal arteriole is increased, then the rate of ultrafiltration will be slower.
