Question

Question: Select the correct sequence for the transport of sperm cells in the male reproductive system.
(A) Testis$ \to $ Epididymis$ \to $ Vasa efferentia$ \to $ Rete testis$ \to $ Inguinal canal$ \to $ Urethra
(B) Seminiferous tubules$ \to $ Rete testis$ \to $ Vasa efferentia$ \to $ Epididymis$ \to $ Vas deferens$ \to $ Ejaculatory duct$ \to $ urethra$ \to $ urethral meatus
(C) Seminiferous tubules$ \to $ Vasa efferentia$ \to $ Epididymis$ \to $ Inguinal canal$ \to $ Urethra
(D) Testis$ \to $ Epididymis$ \to $ Vasa efferentia$ \to $ Vas deferens$ \to $ Ejaculatory duct$ \to $ Inguinal canal $ \to $Urethra$ \to $ Urethral meatus

Answer 1

Hint: The sperm has a pathway of ejaculation that follows the acronym seven up, depicting the above mentioned in a proper sequence. Sperms are found to be formed in the testis which is transported through different parts of the male reproductive system.

Complete answer: The main male reproductive organs include the testis, epididymis, urethra, vas deferens, prostate gland, seminal vesicle, and penis. The testis is formed of seminiferous tubules that are composed of coiled structures that are sites of sperm production. The structure on top of the seminiferous tubules in the epididymis. The sperm move from the seminiferous tubules to the epididymis. Sperms are stored in these structures until the time of ejaculation. During the time of sexual intercourse, the sperms are ejaculated in the female vagina, from that very point their journey starts. The sperm swims through the cervix with the help of the medium of fertile cervical mucus and finally moves into the uterus. The Sperm must swim from one end of the womb of the female to the other to finally reach the female’s fallopian tube.
Hence, the correct answer is option (B). Seminiferous tubules$ \to $ Rete testis$ \to $ Vasa efferentia$ \to $Epididymis$ \to $ Vas deferens$ \to $ Ejaculatory duct$ \to $ urethra$ \to $ urethral meatus.

Note: The process of ejaculation starts as the penis filled by the blood and becomes erect. After sufficient stimulation is given, mature sperm move from the epididymis through the vas deferens, a muscular tube, which pushes sperm forward through smooth contractions. The sperm then reaches first at the ampulla, seminal fluid is added which is propelled through the ejaculatory ducts toward the urethra passing through the prostate gland which makes the semen milky which is ready to be ejected in the urethra.
