Diuresis is the condition in which

Options

A. The excretion of volume of urine increases
B. The excretion of volume of urine decreases
C. The kidney fails to excrete urine
D. The water balance of the body is disturbed.

Answer

**Step-by-Step Solution:**

1. **Understanding Diuresis**: Diuresis refers to a condition characterized by an increased excretion of urine. This is the fundamental definition we need to establish.

2. **Causes of Diuresis**: Diuresis can occur due to two main reasons:
- The absence of Antidiuretic Hormone (ADH).
- Intake of a large volume of water in a short period.

3. **Role of ADH**:
- ADH, or Antidiuretic Hormone, is responsible for the reabsorption of water in the kidneys.
- When ADH is absent, the kidneys stop reabsorbing water, leading to the production of a larger volume of urine.

4. **Consequences of High Water Intake**:
- Consuming a large amount of water also results in increased urine output because the body needs to eliminate the excess water.

5. **Diabetes Insipidus**:
- A specific condition related to diuresis is diabetes insipidus, which occurs when there is a deficiency of ADH, resulting in excessive urination.

6. **Conclusion**: Based on the definitions and causes discussed, we conclude that diuresis is the condition in which the excretion of volume of urine increases.

7. **Final Answer**: The correct answer is: "The excretion of volume of urine increases."
