The shared termminal duct of the reproductive and urinary system in the human male is:A. urethraB. ureterC. vas deferensD. vesa efferentia |
|
Answer» Correct Answer - A (a) In the human male, urethra provides an xit for urine from the urinary bladder as well as semen from vasa differentia during ejaculation. Thus, it is also known as urogential duct. In males, it is about 8 inches (20 cm) long and opens at the end of the penis. Vas deferens and vasa efferentia are the male sex accessory ducts. Ureters are the tubes that carry urine fron the kidney to urinary bladder. |

Which of the following depicts the correct pathway of transport of sperms?A. `"Rete tesstis"rarr"Efferent ductules"rarr"Epididymis"rarr"Vas deferens"`B. `"Rete testis"rarr"Epididymis"rarr"Efferent ductules"rarr"Vas deferens"`C. `"Rete testis"rarr"Vas deferens"rarr"Efferent ductules"rarr"Epitidymis"`D. `"Efferent ductules"rarr"Rete testis"rarr"Vas deferens"rarr"Epididymis"` |
|
Answer» Correct Answer - A (a) The sperms are produced in the seminiferous tubules. The rete testis is connected to those tubules at one end and transfers sperms to vasa efferentia (small tubular structures between rete testis and epididymis). The sperms reah to epididymis through vasa efferentia where they are temporarily stored for maturation and then transfered to seminal vesicle through vas deferens. Thus, the correct route is |
