Question

Select the correct sequence for transport of sperm cells in male reproductive system.

• A. Testis $\to$Epididymis $\to$ Vasa efferentia $\to$ Vas deferens $\to$ Ejaculatory duct $\to$ Inguinal canal
  $\to$ Urethra $\to$ Urethral meatus
• B. Testis $\to$ Epididymis $\to$ Vasa efferentia $\to$ Rete testis $\to$ Inguinal canal $\to$ Urethra
• C. Seminiferous tubules $\to$ Rete testis $\to$ Vasa efferentia $\to$ Epididymis $\to$ Vas deferens $\to$ Ejaculatory
  duct $\to$ Urethra $\to$ Urethral meatus
• D. Seminiferous tubules $\to$ Vasa efferentia $\to$ Epididymis $\to$ Inguinal canal $\to$ Urethra

Answer 1

The correct option is C Seminiferous tubules $\to$ Rete testis $\to$ Vasa efferentia $\to$ Epididymis $\to$ Vas deferens $\to$ Ejaculatory

duct $\to$ Urethra $\to$ Urethral meatus
Sperms are produced in the seminiferous tubules of testis.

The seminiferous tubules open into rete testis which in turn opens into fine ductules called vasa efferentia.

Vasa efferentia leave the testis and open into epididymis which is located along the posterior surface of each testis.

Epididymis opens into vas deferens which ascends and enters into the abdomen and loops over the urinary bladder.

The vas deferens receives a duct from the seminal vesicle and together they join to form the ejaculatory duct which opens into the urethra.

The urethra extends through the penis to its external opening called urethral meatus.

Hence, the correct sequence for transport of sperm cells in male reproductive system is:

Seminiferous tubules → rete testis → vasa efferentia → epididymis → vas deferens → ejaculatory duct → urethra → urethral meatus.
