Select the incorrect match.

Options

A. ANF - Atria of heart
B. Renin - Kidney
C. Vasopressin - Anterior pituitary
D. Progesterone - Placenta

Answer

To solve the question of selecting the incorrect match, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Analyze the First Option: ANF and Artery of Heart**
- ANF stands for Atrial Natriuretic Factor. It is a hormone secreted by the heart's atria, specifically in response to atrial stretch due to increased blood volume.
- **Conclusion**: This match is correct as ANF is related to the heart.

**Hint**: Remember that ANF is secreted by the heart and plays a role in regulating blood pressure and volume.

2. **Analyze the Second Option: RANIN and Kidney**
- RANIN is an enzyme that is involved in the renin-angiotensin system. It is secreted by the kidneys, particularly by the juxtaglomerular cells in response to low blood pressure.
- **Conclusion**: This match is correct as RANIN is indeed associated with the kidneys.

**Hint**: RANIN is crucial for blood pressure regulation and is produced in the kidneys.

3. **Analyze the Third Option: Vasopressin and Anterior Pituitary**
- Vasopressin, also known as Antidiuretic Hormone (ADH), is actually produced in the hypothalamus and released from the posterior pituitary gland.
- **Conclusion**: This match is incorrect because vasopressin is not associated with the anterior pituitary.

**Hint**: Remember that vasopressin is released from the posterior pituitary and is important for water retention in the body.

4. **Analyze the Fourth Option: Progesterone and Placenta**
- Progesterone is a hormone that is primarily produced by the ovaries, but it is also secreted by the placenta during pregnancy.
- **Conclusion**: This match is correct as progesterone is associated with the placenta during pregnancy.

**Hint**: Progesterone plays a key role in maintaining pregnancy and is produced by both the ovaries and the placenta.

### Final Conclusion:
The incorrect match is **Vasopressin and Anterior Pituitary** (Option 3).

### Summary of Incorrect Match:
- **Incorrect Match**: Vasopressin (ADH) is released from the posterior pituitary, not the anterior pituitary.
