ANF secretes by the cells of

Options

A. Right ventricle of heart
B. Right atria of heart
C. Both atria of heart
D. Left ventricle of heart

Answer

**Step-by-Step Solution:**

1. **Understanding ANF**: ANF stands for Atrial Natriuretic Factor. It is a hormone that plays a crucial role in regulating blood pressure and fluid balance in the body.

2. **Identifying the Source of ANF**: The question asks where ANF is secreted from. It is important to know that ANF is secreted by the heart.

3. **Determining the Specific Location**: ANF is specifically secreted by the cells located in the atria of the heart. The heart consists of two atria (right and left) and two ventricles (right and left).

4. **Eliminating Incorrect Options**:
- The right ventricle and left ventricle are not involved in the secretion of ANF, so those options can be eliminated.
- The term "both atria" suggests that ANF is secreted by both the right and left atria, which is not correct as ANF is primarily secreted by the right atrium.

5. **Final Conclusion**: Therefore, the correct answer is that ANF is secreted by the cells of the **right atrium of the heart**.

**Final Answer**: ANF is secreted by the cells of the **right atrium of the heart**.
