Biology Question on human reproduction
If for some reason, the vasa efferentia in the human reproductive system get blocked, the gametes will not be transported from
A
testes to epididymis
B
epididymis to vas deferens
C
ovary to uterus
D
vagina to uterus
Answer
testes to epididymis
Explanation
Solution
Vasa efferentia are fine ciliated ductules that arise from the seminiferous tubules of testis (where sperms are formed) and open into epididymis which is a mass of long narrow closely coiled tubule lying along the inner side of testis. Epididymis stores the sperms. Thus, if vasa efferentia get blocked, sperms will not be transported from testes to epididymis.
