Which gland is concerened with salt equilibrium in body

Options

A. Anterior pituitary
B. Pancreas
C. Adrenal
D. Thyroid

Answer

**Step-by-Step Solution:**

1. **Identify the Gland**: The gland responsible for maintaining salt equilibrium in the body is the adrenal gland.

2. **Function of the Adrenal Gland**: The adrenal glands are endocrine glands that produce various hormones, including adrenaline, steroids, and cortisol.

3. **Focus on Mineralocorticoids**: Within the adrenal glands, the zona glomerulosa is the specific region that produces mineralocorticoids.

4. **Role of Aldosterone**: The primary mineralocorticoid produced is aldosterone. This hormone plays a crucial role in regulating salt and water balance.

5. **Mechanism of Action**: Aldosterone acts mainly on the renal tubules in the kidneys. It stimulates the reabsorption of sodium ions (Na+) and water, which helps to maintain blood pressure and fluid balance.

6. **Excretion of Ions**: In addition to promoting sodium reabsorption, aldosterone also facilitates the excretion of potassium ions (K+) and phosphate ions from the body.

7. **Conclusion**: Therefore, the adrenal gland, through the action of aldosterone, is primarily responsible for maintaining salt equilibrium in the body.

**Final Answer**: The gland concerned with salt equilibrium in the body is the adrenal gland.
