According to the text, the seminiferous tubules of the testis open into the vasa efferentia through the rete testis. The vasa efferentia leave the testis and open into the epididymis. The epididymis leads to the vas deferens, which ascends to the abdomen and opens into the urethra as the ejaculatory duct. The urethra extends to its external opening called the urethral meatus. Thus, the correct sequence is: Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → Urethra → Urethral meatus , .
