In humans, vasa efferentia leaves the testis and opens into epididymis located along the

• A. Anterior surface of testis.
• B. Lower surface of testis.
• C. Posterior surface of testis.
• D. Superior surface of testis

Answer 1

Answer: (C)

Vasa efferentia: 12–20 fine tubules called vasa efferentia or ductuli efferentes connect caput epididymis and rete testis. Their epithelium lining is ciliated for conducting sperms. Tubuli recti, rete testis, and ductuli efferentes constitute an intratesticular genital duct system. The cells of vasa efferentia are columnar-ciliated.
The pathway for the movement of sperm in the male reproductive tract is as follows:
