Question

The pressure which favours filtration of blood in the kidney and the one which opposes the filtration of blood are .......... and ........... respectively.

• A. Glomerular hydrostatic pressure and glomerular osmotic pressure
• B. Capsular hydrostatic pressure and glomerular osmotic pressure
• C. Glomerular osmotic pressure and glomerular hydrostatic pressure
• D. Glomerular osmotic pressure and arterial pressure

Answer 1

Answer: (A)

Glomerular hydrostatic pressure and glomerular osmotic pressure

Hydroststic pressure is the pressure of the fluid that is created on the walls of the glomerulus or bowmans capsule. This is exactly the blood pressure in the glomerulus that helps in the filtration of more blood in the glomerulus in the unit time.

Another pressure osmotic pressure or the oncotic pressure is exerted in the glomerulus by the colloids that are the proteins albulin. These colloids creates opposite preusure.

Hence, the option A is correct.
