Which one of the following function is not related to hormones of adrenal cortex of adrenal gland?

Options

A. It regulate the balance of water and electrolyte in human body.
B. It stimulate RBC production of erythropoiesis .
C. It maintain emergency situations or 3 'F' conditions.
D. It suppresses the immune response/system .

Answer

To solve the question "Which one of the following function is not related to hormones of adrenal cortex of adrenal gland?", we need to understand the functions of the hormones produced by the adrenal cortex.

### Step-by-Step Solution:

1. **Identify the Parts of the Adrenal Gland**: The adrenal gland consists of two main parts: the adrenal cortex and the adrenal medulla.

2. **Understand the Hormones of the Adrenal Cortex**:
- The adrenal cortex produces three main types of hormones:
- **Mineralocorticoids** (e.g., Aldosterone): Regulates water and electrolyte balance.
- **Glucocorticoids** (e.g., Cortisol): Regulates carbohydrate metabolism, suppresses the immune system, and has anti-inflammatory effects.
- **Androgens**: Involved in the development of secondary sexual characteristics.

3. **Identify Functions of Each Hormone**:
- **Aldosterone**: Involved in the absorption of sodium and water, thus regulating blood pressure and fluid balance.
- **Cortisol**: Affects metabolism, suppresses the immune response, and promotes erythropoiesis (RBC production).
- **Androgens**: Responsible for the development of male and female secondary sexual characteristics.

4. **Evaluate the Given Options**: The question asks which function is NOT related to the hormones of the adrenal cortex.
- Functions related to the adrenal cortex include:
- Regulation of water and electrolyte balance (Aldosterone).
- Suppression of immune response and regulation of carbohydrate metabolism (Cortisol).
- Development of secondary sexual characteristics (Androgens).
- Functions related to the adrenal medulla (not adrenal cortex) include:
- Fight or flight response (e.g., increased heart rate, glucose levels).

5. **Select the Correct Answer**: Based on the analysis, the function that is not related to the adrenal cortex hormones is the one associated with the adrenal medulla's response to emergency situations. Therefore, the correct answer is the option that describes a function related to the adrenal medulla.

### Conclusion:
The function that is not related to the hormones of the adrenal cortex is the one associated with the adrenal medulla, which is typically linked to the fight or flight response.
