$\begin{array}{cc}\text{Column 1}& \text{Column 2}\\ \text{A)Proximal convoluted tubule}& \text{1) Formation of concentrated urine}\\ \text{B)Distal convoluted tubule}& \text{2) Filtration of blood}\\ \text{C)Henle’s loop}& \text{3) 70-80\% reabsorption}\\ \text{D)Countercurrent mechanism}& \text{4) ionic balance}\\ \text{E)Renal corpuscle}& \text{5) Maintenance of concentration}\\ & \text{gradient in medulla}\end{array}$

• A. A-3, B-2, C-5, D-1, E-4
• B. A-4, B-2, C-5, D-3, E-1
• C. A-3, B-4, C-5, D-1, E-2
• D. A-3, B-4, C-5, D-1, E-2

Answer 1

The correct option is C A-3, B-4, C-5, D-1, E-2

Proximal convoluted tubule is responsible for 70-80% of reabsorption of mineral ions and water.
Distal convoluted tubule helps in maintaining ionic balance.
Henle’s loop helps in the maintenance of concentration gradient in the renal medulla.
Counter current mechanism helps in the formation of concentrated urine.
Renal corpuscle helps in filtration of blood.
