Current Question (ID: 14712)

Question:

During counter current mechanism, interstitial medullary concentration can be increased up to 4 times due to

Options:

1. i, ii, iii & iv
2. i & ii
3. ii & iii
4. i only

Solution:

During the counter current mechanism, the interstitial medullary concentration can be increased up to 4 times due to active pumping of salts from the upper part of the ascending limb and passive diffusion of salts from the lower part of the ascending limb. This generates a concentration gradient that allows for the passive diffusion of Na⁺ and Cl⁻ from the thin segment of the ascending limb into the interstitium. Therefore, the correct statements are i and ii: active pumping of salts from the upper part of the ascending limb and passive diffusion of salts from the lower part of the ascending limb. Option 3 (ii and iii) and Option 4 (i only) are incorrect because they do not include all the correct statements. Option 1 (i, ii, iii, and iv) is incorrect because option iv, active secretion of Na⁺ and Cl⁻ into the thin segment of the tubule, is not a correct statement.
