NTA AbhyasNTA Abhyas 2020
Solution:
Spermatogenesis is carried out in the seminiferous tubules of the testes, where the germ cells develop into male gametes with the help of Sertoli cells and androgens. These tubules are linked to the vasa efferentia via the rete testis. The vasa efferentia opens into another accessory duct called the epididymis, which opens into the ductus deferens (vas deferens), which ascends to the abdomen and loops over the urinary bladder. It receives a duct from the seminal vesicles, which opens into the urethra as the ejaculatory duct. This duct carries sperms outside the body through the process of ejaculation.
Thus, the correct flow of sperms includes:
Seminiferous tubules $ \rightarrow $ Rete testis $ \rightarrow $ Vasa efferentia $ \rightarrow $ Epididymis $ \rightarrow $ Vas deferens $ \rightarrow $ Ejaculatory duct $ \rightarrow $ Urethra $ \rightarrow $ Penis
