Question

15. Which of the folliowing is true?
(1) GHP is due to plasma proteins
(2)
BCOP is due to narrower afferent arterioles
(3) Fall in blood pressure tends to reduce EFP
(4)
Fall in blood pressure increases both EFP and CHP​

Answer 1

Answer:

the 3rd answer is true

Explanation:

Answer 2

Which of the following is true?

Explanation:

• The various pressures on which effective filtration pressure (EFP) is dependent are arterial blood pressure in the glomerular capillaries (GHP), blood colloid osmotic pressure (BCOP) and capsular hydrostatic pressure in the Bowman's capsule (CHP).
• The kidney has capability to tackle with a wide range of blood pressures.
• In large part, it is because of the autoregulatory nature of smooth muscle.
• When the muscle is stretched, it contracts.
• Therefore, when blood pressure rises, smooth muscle in the afferent capillaries get contracted to reduce any increase in blood flow and filtration rate and similarly when blood pressure falls down, the same capillaries dilate to maintain blood flow and filtration rate.
• Equation: EFP = GHP - (BCOP+ CHP)
• Hence, the correct answer is (3) Fall in blood pressure tends to reduce EFP.
