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 bu JG cells

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 between Column I and Column II, we will analyze each item in Column I and find the corresponding item in Column II based on their functions and characteristics.

### Step-by-Step Solution:

1. **Identify ADH (Antidiuretic Hormone)**:
- ADH is primarily responsible for regulating water balance in the body by promoting water reabsorption in the kidneys.
- It is released from the posterior pituitary gland.
- **Match**: ADH (a) → Released from pituitary gland (iii).

2. **Identify Renin**:
- Renin is an enzyme that plays a crucial role in the Renin-Angiotensin-Aldosterone System (RAAS), which regulates blood pressure.
- It is secreted by the juxtaglomerular (JG) cells in the kidneys.
- **Match**: Renin (b) → Released by JG cells (iv).

3. **Identify ANF (Atrial Natriuretic Factor)**:
- ANF is involved in the regulation of blood pressure and fluid balance. It acts as a vasodilator, promoting the excretion of sodium and water, which lowers blood pressure.
- **Match**: ANF (c) → Vasodilator (ii).

4. **Identify Angiotensin II**:
- Angiotensin II is a potent vasoconstrictor that increases blood pressure by constricting blood vessels.
- **Match**: Angiotensin II (d) → Vasoconstrictor (i).

### Final Matches:
- a → iii (ADH → Released from pituitary gland)
- b → iv (Renin → Released by JG cells)
- c → ii (ANF → Vasodilator)
- d → i (Angiotensin II → Vasoconstrictor)

### Conclusion:
The correct matches are:
- a → iii
- b → iv
- c → ii
- d → i
