Rete testes open into which of the following structures?
Vas deferns
Vas efferentia
Epididymis
Seminal vesicles
The male sex accessory ducts include rete testis, vasa efferentia, epididymis and vas deferens.
The seminiferous tubules of the testis open into the vasa efferentia through rete testis.
The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis.
Hence option B is correct.
