If for some reason, the vas efferentia in the human reproductive system get blocked, the gametes will not be transported from:
Correct answer: A. Testes to epididymis
- A. Testes to epididymis
- B. Epididymis to vas deferens
- C. Ovary to uterus
- D. Vagina to uterus
Explanation
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. So if vasa efferentia gets blocked, the gametes will not be transported from testes to epididymis.
