Question

when released, mature sperm leave the epididymis and travel through the

• penis
• urethra
• scrotum
• vas deferens

Explanation:

🆕 New Concept Discovered: Human Reproductive Anatomy
The pathway of gametes through the reproductive system.

Step 1: Identify the function of the epididymis

The epididymis is a coiled tube located on the back of each testis. Its primary function is to store and allow for the maturation of sperm cells.

Step 2: Trace the path of sperm during ejaculation

When ejaculation occurs, mature sperm leave their storage site in the epididymis. They must travel from the testes up into the pelvis to reach the urethra. The muscular duct that carries them directly out of the epididymis is the vas deferens (also known as the sperm duct).

Step 3: Evaluate the options

• penis: This is the external organ through which semen is delivered, but it is not the immediate duct sperm enter upon leaving the epididymis.
• urethra: This is the tube that carries urine and semen out of the body, which sperm reach much later in the pathway after passing through the vas deferens and ejaculatory ducts.
• scrotum: This is the external pouch of skin containing the testes, not a tube or duct for sperm transport.
• vas deferens: This is the direct tube that connects the epididymis to the ejaculatory ducts, serving as the immediate next step in the pathway.

Answer:

vas deferens
