Options

A. elimination of sodium , potassium and water.
B. conservation of sodium, potassium and water.
C. conservation of potassium and water and elimination of sodium.
D. conservation of sodium and water and elimination of potassium

Answer

**Step-by-Step Solution:**

1. **Understanding Aldosterone:**
- Aldosterone is a hormone produced in the adrenal cortex, which is part of the adrenal glands located above the kidneys.

2. **Function of Aldosterone:**
- The primary role of aldosterone is to regulate electrolyte balance in the body. It affects various organs, particularly the kidneys, salivary glands, and sweat glands.

3. **Mechanism of Action:**
- Aldosterone acts on the kidneys to increase sodium reabsorption into the bloodstream. This means that more sodium is retained in the body rather than being excreted in urine.

4. **Potassium Regulation:**
- Alongside sodium conservation, aldosterone promotes the excretion of potassium ions into the urine. This helps maintain the proper balance of electrolytes in the body.

5. **Water Conservation:**
- By promoting sodium reabsorption, aldosterone indirectly aids in water conservation. Since water follows sodium, retaining sodium also leads to the retention of water in the body.

6. **Final Conclusion:**
- Therefore, aldosterone helps in the conservation of sodium and water while facilitating the elimination of potassium.

**Final Answer:**
Aldosterone helps in the conservation of sodium and water and the elimination of potassium.
