Match the pair.
| Column I (Type of pressure during ultrafiltration) | Column II (values) |
|---|---|
| (A) Glomerular hydrostatic pressure | (I) 30 mm of Hg |
| (B) Opposing osmotic pressure of blood | (II) 15 mm of Hg |
| (C) Opposing capsular pressure | (III) 10 mm of Hg |
| (D) Net filtration pressure | (IV) 55 mm of Hg |
Choose the correct option
Options:
Answer:
Solution:
Glomerular hydrostatic pressure is the pressure of blood in the glomerular capillaries, which is approximately mm of Hg.
Opposing osmotic pressure of blood is the colloidal osmotic pressure due to plasma proteins, which opposes filtration and is about mm of Hg.
Opposing capsular pressure is the hydrostatic pressure exerted by the fluid already present in the Bowman's capsule, which is about mm of Hg.
Net filtration pressure is the effective pressure driving the ultrafiltration process. It is calculated as the difference between the glomerular hydrostatic pressure and the sum of the opposing pressures.
Net filtration pressure mm of Hg.
Thus, the correct matching is A - IV, B - I, C - II, D - III.
Answer: A - IV, B - I, C - II, D - III
