Question 16

The organ that is part of both the male reproductive system and urinary system is the urethra.

The urethra serves a dual function in males, as it is responsible for the passage of urine from the bladder as well as the expulsion of semen during ejaculation.

A) Epidermis

The epidermis is the outermost layer of skin and is not involved in either the reproductive or urinary systems. This option is completely unrelated to the question.

B) Ureter

The ureter is a tube that carries urine from the kidneys to the bladder. While it is part of the urinary system, it does not play a role in the male reproductive system, making this option incorrect.

C) Testis

The testis is a key component of the male reproductive system, responsible for producing sperm and hormones. However, it is not part of the urinary system, thus this option does not satisfy the requirement of being part of both systems.

D) Urethra

The urethra is indeed a part of both the male reproductive system and the urinary system. It allows for the passage of urine as well as the delivery of semen during sexual activity, making this option the correct answer.

Conclusion

The urethra is the only organ listed that functions in both the male reproductive and urinary systems, fulfilling the criteria of the question. Other options either relate to only one of the systems or are entirely unrelated, underscoring the uniqueness of the urethra's dual role.
