Hormones stimulate production of erythrocytes are

Options

A. Aldosterone,Calcitonin,Cortisol
B. Erythropoietin,Thyrocalcitonin,Growth Horomone
C. Cortisol,Thyroxine,Erythropoietin
D. Thyoxine ,Epinephrine,Erythropoietin

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for hormones that stimulate the production of erythrocytes (red blood cells).

2. **Understand Erythropoiesis**: Erythropoiesis is the process of red blood cell production. Several hormones play a role in this process.

3. **Identify Key Hormones**:
- The primary hormone responsible for stimulating erythropoiesis is **Erythropoietin (EPO)**.
- Erythropoietin is produced mainly in the kidneys and is crucial for the formation of red blood cells.

4. **Additional Hormones**:
- **Thyroid Hormones**: These hormones, particularly **Thyroxine (T4)**, also play a role in stimulating the production and maturation of red blood cells.
- **Cortisol**: This hormone, secreted by the adrenal cortex, has effects on erythropoiesis as well, primarily through its anti-inflammatory responses and its role in stimulating red blood cell production.

5. **Summarize the Hormones**: The three hormones that stimulate the production of erythrocytes are:
- Erythropoietin
- Thyroxine (T4)
- Cortisol

6. **Conclusion**: Therefore, the answer to the question is that the hormones stimulating the production of erythrocytes are Erythropoietin, Thyroxine, and Cortisol.
