Question

Which of the following is correct about the path of sperm during ejaculation and the glands involved with the male reproductive system?
A. Vas deferens, testis, urethra, seminal vesicle and prostate gland
B. Testis, vas deferens, seminal vesicle, prostate gland and urethra
C. Urethra, vas deferens, testis, seminal vesicle and prostate gland
D. Seminal vesicle and prostate gland, vas deferens, testis, urethra

Answer 1

Hint: When the process of ejaculation takes place, the sperms are forcefully expelled from the tail of the epididymis into the vas deferens. The sperm afterward travels through the vas deferens to the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder.

Complete answer: In a male reproductive system, ejaculation is the release of sperm cells and seminal plasma. The vas deferens is the tiny muscular tube that carries the sperm from the epididymis to the ejaculatory duct. The testis is the male reproductive gland present in all animals, including humans. The functions of the testes are to produce both the sperm and the androgens, primarily testosterone. The urethra is a thin, fibromuscular tube that begins at the lower opening of the bladder and then extends through the pelvic and the urogenital diaphragms to the outside of the body. The urethra also connects to the ductus deferens in males, for the ejaculation of the sperm. The seminal vesicles are the pair of glands found in the male pelvis, which function to produce many of the constituent ingredients of the semen. The prostate gland is walnut-sized located between the bladder and the penis. The prostate is presented just in front of the rectum. The urethra runs through the center of the prostate, from the bladder to the penis, letting the urine go out of the body. The sperms are produced in the testes and enter the ejaculatory ducts through the vas deferens. Then it enters into the urethra to the seminal vesicle. As it passes by the seminal vesicle, a fluid-rich in fructose combines with the sperm. This adds nourishments to the sperm in order to keep it active and motile.
Therefore, the correct answer is option B.

Note: The pathway begins with the spermatogenesis in the seminiferous tubules, transport through the fluid gradients in the epididymis, peristalsis in the vas deferens, and expulsion in the ejaculatory ducts. At this point, the nutrients are added to the semen before it makes its way through the urethra and the penis before becoming ejaculate.
