Question

Match the following:
$\begin{array}{cc}\text{Column I}& \text{Column II}\\ \text{i.Pressure filtration}& \text{a. Urea and uric acid}\\ \text{ii. Selective reabsorption}& \text{b.Penicillin}\\ \text{iii.Tubular secretion}& \text{c. Water, glucose, amino acids}\\ \text{iv. Excretion}& \text{d. Water, glucose, urea}\end{array}$

• A. i) $\Rightarrow$ a, ii) $\Rightarrow$ c, iii) $\Rightarrow$ b, iv) $\Rightarrow$ d
• B. i) $\Rightarrow$ d, ii) $\Rightarrow$ c, iii) $\Rightarrow$ b, iv) $\Rightarrow$ a
• C. i) $\Rightarrow$ c, ii) $\Rightarrow$ b, iii) $\Rightarrow$d, iv) $\Rightarrow$ a
• D. i) $\Rightarrow$ a, ii) $\Rightarrow$ d, iii) $\Rightarrow$ b, iv) $\Rightarrow$ c

Answer 1

The correct option is B

i) $\Rightarrow$ d, ii) $\Rightarrow$ c, iii) $\Rightarrow$ b, iv) $\Rightarrow$ a

Pressure filtration - Blood pressure forces molecules from the blood into the glomerular capsule. Examples of molecules - water, glucose, urea. Selective reabsorption - Diffusion and active transport, return molecules to blood at the proximal distal convoluted tubule. Example of molecules - water, glucose, amino acids. Tubular secretion - Active transport moves molecules from blood into the distal convoluted tubule. Example of molecules - penicillin.

Excretion - Urine formation aids the body to get rid of metabolic waste. Example of molecules - Urea and uric acid.
