Which one of the following statement is correct respect to kidney function regulation

Options

A. When someone drinks lot of water, ADH release is suppressed.
B. Exposure to cold temperature stimulates ADH release
C. An increase in glomerular blood flow stimulate formation of Angiotensin II
D. During summer when body loses lot of water by evaporation, the release of ADH is suppressed

Answer

To determine which statement regarding kidney function regulation is correct, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Analyze Statement A**: "When someone drinks a lot of water, ADH release is suppressed."
- The anti-diuretic hormone (ADH) is responsible for increasing water reabsorption in the kidneys. When a person consumes a large amount of water, the body does not need to reabsorb more water, leading to a suppression of ADH release. This statement is **correct**.

2. **Analyze Statement B**: "Exposure to cold temperature stimulates ADH release."
- Cold temperatures often lead to reduced fluid intake. In response to lower water availability, the body increases ADH levels to promote water reabsorption. Therefore, this statement is also **correct**.

3. **Analyze Statement C**: "An increase in glomerular blood flow stimulates formation of angiotensin II."
- Angiotensin II is primarily formed in response to low blood pressure or low blood volume, not an increase in glomerular blood flow. Therefore, this statement is **incorrect**.

4. **Analyze Statement D**: "During summer, when the body loses a lot of water by evaporation, the release of ADH is suppressed."
- In summer, when the body loses water through evaporation, the body needs to conserve water. Thus, ADH levels would actually increase to promote water reabsorption, making this statement **incorrect**.

### Conclusion:
The correct statement regarding kidney function regulation is **Statement A**: "When someone drinks a lot of water, ADH release is suppressed."
