Which one of the following shows the correct sequence of the path of urine in the human excretory system?

Options

A. Kidney `to` urinary bladder `to` ureter `to` urethra
B. Kidney `to` ureter `to` urinary bladder `to` urethra
C. Kidney `to` urinary bladder `to` urethra `to` ureter
D. Kidney `to` urethra `to` urinary bladder `to` ureter

Explanation

To determine the correct sequence of the path of urine in the human excretory system, we can break down the process into clear steps:

### Step-by-Step Solution:

1. **Formation of Urine in the Kidney**:
- The process begins in the kidneys, where blood is filtered to form urine. The kidneys remove waste products and excess substances from the blood.

2. **Transport through the Ureters**:
- Once urine is formed, it is transported from the kidneys to the urinary bladder through the ureters. The ureters are muscular tubes that carry urine by peristaltic movements.

3. **Storage in the Urinary Bladder**:
- The urine is stored in the urinary bladder, a hollow muscular organ that can expand to hold urine until it is ready to be excreted.

4. **Excretion through the Urethra**:
- Finally, when the bladder is full and the body is ready to excrete urine, it passes through the urethra, which is the tube that carries urine out of the body.

### Correct Sequence:
- Therefore, the correct sequence of the path of urine in the human excretory system is:
**Kidney → Ureter → Urinary Bladder → Urethra**.

### Conclusion:
- Based on the explanation, the correct answer is **Option C**: Kidney to Ureter to Bladder to Urethra.
