The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Micturition**: Micturition is a medical term that refers to the process of urination. It is important to clarify what this term means in the context of excretion. 2. **Identifying the Process**: Micturition involves the release of urine from the urinary bladder. The urine is expelled through the urethra, which is the tube that carries urine out of the body. 3. **Mechanism of Micturition**: The process of micturition occurs when the bladder neck and the external urinary sphincter relax. This relaxation allows for the unobstructed flow of urine from the bladder to the outside of the body. 4. **Differentiating from Other Processes**: It is essential to differentiate micturition from other excretory processes: - Removal of urea from blood occurs in the kidneys and is part of the filtration process. - Removal of uric acid is a different process known as uricosuria. - The removal of feces is termed defecation, which is unrelated to urine. 5. **Conclusion**: Based on the above points, the correct definition of micturition is the passing out of urine. ### Final Answer: Micturition is the passing out of urine. ---
