The ______________________ hormone helps in the maintenance of electrolytes .

Options

A. Aldosterone
B. Androgenic steroids
C. Corticoids
D. Adrenaline

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the hormone responsible for maintaining electrolytes in the body.

2. **Defining Electrolytes**: Electrolytes are substances that dissociate into ions in solution and are essential for various bodily functions, including maintaining fluid balance, nerve function, and muscle function. Common electrolytes include sodium, potassium, calcium, and chloride.

3. **Identifying Relevant Hormones**:
- **Aldosterone**: This hormone is produced by the adrenal glands and plays a crucial role in regulating sodium and potassium levels in the body. It promotes the reabsorption of sodium in the kidneys, which helps maintain electrolyte balance.
- **Androgenic Steroids**: These are primarily involved in the development of male characteristics and do not play a significant role in electrolyte balance.
- **Corticosteroids**: While they have various functions, they are more related to stress response and metabolism rather than direct electrolyte maintenance.
- **Adrenaline**: This hormone is involved in the body's fight-or-flight response and does not regulate electrolyte balance.

4. **Conclusion**: Based on the functions of the hormones discussed, aldosterone is the hormone that specifically helps in the maintenance of electrolytes by regulating sodium and potassium levels in the kidneys.

5. **Final Answer**: The hormone that helps in the maintenance of electrolytes is **aldosterone**.
