Question

The correct sequence of organs in the male reproductive system for transport of sperms is

• A. testis $\to$ vas deferent $\to$ urethra
• B. testis $\to$ ureter $\to$ urethra
• C. testis $\to$ urethra $\to$ ureter
• D. testis $\to$ vasdeferens $\to$ ureter

Answer 1

The correct option is D

testis $\to$ vasdeferens $\to$ ureter

The correct option is D.

Explanation for the correct option:

1. Sperm are produced in the testicles, stored in the epididymis, and transported to the urethra by vas deferens.
2. Sperm produced in the testicles are stored in a tube called the epididymis.
3. Here the sperm matures and travels to the urethra through a muscular tube called vas deferens.

Testicles:

1. The testicles are responsible for making testosterone, the primary male sex hormone, and producing sperm.
2. Inside the testicle is a wrapped mass of tubes called seminiferous tubules is present.
3. These tubules are responsible for the production of sperm cells through a process called spermatogenesis.

Vas deferens:

1. A coiled tube that carries sperm out of the testicles.
2. The sperm is transferred from the vas deferens into the urethra, collecting secretions from the male accessory sex glands such as the seminal vesicles and the prostate gland.

Ureter:

1. The ureters are narrow, hollow, muscular tubes, approximately nine inches long, that connect the kidneys to the bladder.
2. In males, the urethra (size- 20 cm) allows for the expulsion of both urine and semen.

Final answer: The correct sequence of organs in the male reproductive system for transport of sperms is testis $\to$ vasdeferens $\to$ ureter.
