Open in App
Solution
The correct option is A Vas deferens
Accessory ducts in males
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.
Final answer
(D) Vas deferens
