Question:
The path of the sperm transport is shown below. Identify P and Q and select the correct option.
Seminiferous tubules → Rete testis → P → Epididymis → Q → Urethra
The path of the sperm transport is shown below. Identify P and Q and select the correct option.
| Seminiferous tubules | → | Rete testis | → | P | → | Epididymis | → | Q | → | Urethra |
Show Hint
Sperm go from the rete testis to the epididymis through the vasa efferentia. From the epididymis they go to the urethra through the vas deferens.

- P - Vasa efferentia, Q - Ureter
- P - Ejaculatory duct, Q - Vas deferens
- P - Vasa efferentia, Q - Vas deferens
- P - Vas deferens, Q - Vasa efferentia

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Write the full path of sperm:
Sperm are made in the seminiferous tubules of the testis. They move into the rete testis.
From the rete testis they pass through fine tubules called vasa efferentia and leave the testis.
The vasa efferentia open into the epididymis, where sperm mature and are stored.
From the epididymis the sperm go into the vas deferens. It carries them to the urethra through the ejaculatory duct.
Step 2: Match the boxes:
P lies between the rete testis and the epididymis. So P is the vasa efferentia.
Q lies between the epididymis and the urethra. So Q is the vas deferens.
Step 3: Check each option:
(A) The ureter carries urine from the kidney. It is not a part of the sperm path. So it is wrong.
(B) The ejaculatory duct comes after the vas deferens, not before the epididymis. So it is wrong.
(C) P is vasa efferentia and Q is vas deferens. This is correct.
(D) This swaps the two structures, so the order is wrong.
Final Answer:
P is the vasa efferentia and Q is the vas deferens, which is option (C).
