Select the correct sequence for transport of sperm cells in male reproductive system.
Answer: (B) Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → Urethra → Urethral meatus. Answer: (B) Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → Urethra → Urethral meatus Solution: NCERT states the seminiferous tubules open into the vasa efferentia through rete testis, the vasa efferentia open into the epididymis, which leads to the vas deferens; this receives a duct from the seminal vesicle and opens into the urethra as the ejaculatory duct, the urethra ending at the urethral meatus.
- A.Testis → Epididymis → Vasa efferentia → Rete testis → Inguinal canal → Urethra
- B.Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → Urethra → Urethral meatus✓
- C.Seminiferous tubules → Vasa efferentia → Epididymis → Inguinal canal → Urethra
- D.Testis → Epididymis → Vasa efferentia → Vas deferens → Ejaculatory duct → Inguinal canal → Urethra → Urethral meatus
Correct Answer
(B) Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → Urethra → Urethral meatus
Solution & Explanation
Answer: (B) Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → Urethra → Urethral meatus Solution: NCERT states the seminiferous tubules open into the vasa efferentia through rete testis, the vasa efferentia open into the epididymis, which leads to the vas deferens; this receives a duct from the seminal vesicle and opens into the urethra as the ejaculatory duct, the urethra ending at the urethral meatus. Only option B follows this exact order. NCERT Reference: Ch 2, p.27, line 41 — "the testis open into the vasa efferentia through rete testis. The vasa efferentia"
