5.ID: 10984919276 Tube that leads from the epididymis to the urethra Vas deferens Cowper duct ureter Bulbourethral duct

The tube that leads from the epididymis to the urethra is called the **vas deferens**. Here's a brief explanation of the options provided: 1. **Vas deferens**: This is the correct answer. It is a muscular tube that transports sperm from the epididymis to the ejaculatory duct, which then leads to the urethra. 2. **Cowper duct**: This is not a correct answer. The Cowper's glands (bulbourethral glands) secrete a pre-ejaculate fluid, but they do not transport sperm. 3. **Ureter**: This is incorrect. The ureters are tubes that carry urine from the kidneys to the bladder. 4. **Bulbourethral duct**: This is also incorrect. The bulbourethral glands secrete a fluid that lubricates the urethra but do not transport sperm. Thus, the correct answer is **vas deferens**.
