KonstantinChe [14]

Correct sequence of sperm-transporting tubules that transport spermatozoa to the epididymis is Seminiferous Tubules---> Rete Testis---> Vasa Efferentia----> Epididymis

Spermatozoa is the sperm that is formed from a spermatid after Spermiogenesis. It is released into the lumen of seminiferous tubules.

Seminiferous Tubules is present in the testis of human body.

Sperm transporting tubules are:

  • Seminiferous Tubules
  • Rete testis
  • Vasa Efferentia
  • Epididymis

The sperm passes through the seminiferous tubule into Rete testis.

Rete testis is a network of tubules that form a link between seminiferous tubule and Vasa Efferentia.

Vasa Efferentia connects Rete testis to Epididymis. It makes a pathway for the sperm transportation.

Epididymis is the region where the transported sperm from Vasa Efferentia reach. It stores the sperm until they are functionally matured enough to carry out the fertilisation in the human female body.

Hence, the pathway is Seminiferous Tubules---> Rete Testis---> Vasa Efferentia----> Epididymis
