Question

Vasa efferentia lead from

• A. Testicular lobules to rete testis
  
• B. Epididymis to urethra
  
• C. Rete testis to vas
  deferens
  
• D. Vas deferens to
  epididymis
  

Answer 1

The correct option is C Rete testis to vas

deferens

Accessory ducts

The accessory ducts in males helps in the storage of spermatozoa and the transport of them outside the urethra during ejaculation. It includes rete testis, vasa efferentia, epididymis and vas deferens.

Rete testis

The seminiferous tubules inside the testes where sperm formation takes place are closed at one end and on the other end they join to a network of tubules called rete testis.

Vasa efferentia

Rete testis joins with vasa efferentia which leaves the testis and opens into epididymis.

Epididymis

Epididymis is located along the posterior side of each testis, which leads to vas deferens.
Vas deferens
Vas deferens ascends to the abdomen and loops over the urinary bladder where it is joined by the duct from the seminal vesicle to form the ejaculatory duct.

Sequence of accessory ducts

Seminiferous tubules in testes open into rete testis which in turn opens into vasa efferentia followed by epididymis, which in turn opens into vas deferens.

Hence the correct sequence of arrangement of accessory duct is as follows:

Seminiferous tubules $\to$ Rete testis $\to$ Vas efferentia $\to$ Epididymis$\to$ Vas deferens

Testicular lobules

Each testis has about $250$ compartments which are called testicular lobules and each lobule contains $1-3$ seminiferous tubules.

Final answer
(A) Rete testis to vas deferens
