Question

Match the following:

Column I	Column II
A. Glomerulus	i. Essential nutrients, 70–80% water and electrolytes are reabsorbed
B. DCT	ii. Maintenance of osmolality
C. PCT	iii. Filtration of blood
D. Henle’s loop	iv. Secretion of H+ and K+ ions

• A. A – iii, B – i, C – ii, D – iv
• B. A – iv, B – i, C – iii, D – ii
• C. A – iii, B – iv, C – i, D – ii
• D. A – iii, B – iii, C – iv, D – i

Hint:

Memorize the nephron parts with their main roles: filtration (glomerulus), reabsorption (PCT), gradient (Henle’s loop), and secretion (DCT).

Answer 1

The Correct Option is C

• A. Glomerulus: Responsible for filtration of blood $\Rightarrow$ iii
• B. DCT (Distal Convoluted Tubule): Involved in the secretion of $H^{+}$ and $K^{+}$ ions $\Rightarrow$ iv
• C. PCT (Proximal Convoluted Tubule): Reabsorbs most essential nutrients and water $\Rightarrow$ i
• D. Henle’s loop: Helps in maintaining osmolality by creating a concentration gradient $\Rightarrow$ ii
