Match the column I and column II and choose the correct option
(Column I) a.ADH b.Renin c.ANF d.angiotensin II
(Column II) i.Vasoconstrictor ii.Vasodilator iii.Released from pituitary gland iv.Released by JG cells
1) a(iii),b(iv),c(I),d(ii)
2) a(iv),b(iii),c(ii),d(i)
3) a(iv),b(iii),c(i),d(ii)
4) a(iii),b(iv),c(ii),d(i)

Options

A. a(iii),b(iv),c(I),d(ii)
B. a(iv),b(iii),c(ii),d(i)
C. a(iv),b(iii),c(i),d(ii)
D. a(iii),b(iv),c(ii),d(i)

Answer

To solve the matching question, we need to analyze the functions and origins of the substances listed in Column I and match them with the appropriate descriptions in Column II.

1. **ADH (Antidiuretic Hormone)**:
- Function: ADH is responsible for the reabsorption of water in the kidneys.
- Origin: It is released from the posterior pituitary gland.
- Match: ADH corresponds to option (iii) in Column II.

2. **Renin**:
- Function: Renin is an enzyme that plays a role in the regulation of blood pressure and fluid balance.
- Origin: It is released by the juxtaglomerular (JG) cells in the kidneys.
- Match: Renin corresponds to option (iv) in Column II.

3. **ANF (Atrial Natriuretic Factor)**:
- Function: ANF is involved in the reduction of blood volume and pressure; it acts as a vasodilator.
- Match: ANF corresponds to option (ii) in Column II.

4. **Angiotensin II**:
- Function: Angiotensin II is a potent vasoconstrictor that increases blood pressure.
- Match: Angiotensin II corresponds to option (i) in Column II.

Now, let's summarize the matches:
- a (ADH) matches with (iii) Released from pituitary gland.
- b (Renin) matches with (iv) Released by JG cells.
- c (ANF) matches with (ii) Vasodilator.
- d (Angiotensin II) matches with (i) Vasoconstrictor.

Putting it all together, the correct matches are:
- a(iii), b(iv), c(ii), d(i)

This corresponds to option 4.

**Final Answer**: Option 4: a(iii), b(iv), c(ii), d(i)
