Hormone released by hypothalamus, which is related with the functioning of kidney is

Options

A. renin
B. ANF
C. vasopressin
D. angiotensin

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for the hormone released by the hypothalamus that is related to kidney function.

2. **List the Options**: The options provided are renin, ANF (Atrial Natriuretic Factor), vasopressin, and angiotensin.

3. **Analyze Each Option**:
- **Renin**: This hormone is released by juxtaglomerular cells in the kidneys and is primarily involved in increasing blood pressure. It is not released by the hypothalamus.
- **ANF (Atrial Natriuretic Factor)**: This hormone acts on the kidneys to increase sodium excretion and its secretion is inhibited by renin. However, it is not released by the hypothalamus.
- **Vasopressin (ADH)**: This hormone, also known as Antidiuretic Hormone, is released by the hypothalamus. It regulates water levels in the body by signaling the kidneys to absorb more water, making it directly related to kidney function.
- **Angiotensin**: This hormone helps maintain blood pressure and fluid balance. It is produced from angiotensinogen, which is secreted by the liver and is broken down by renin. It is not released by the hypothalamus.

4. **Conclusion**: The only hormone among the options that is released by the hypothalamus and is related to kidney function is **vasopressin**.

5. **Final Answer**: The hormone released by the hypothalamus that is related to the functioning of the kidney is **vasopressin**.
