Question

In tracing the path of sperm, you would mention vasa deferentia before
(a)Testis
(b)Epididymis
(c)Urethra
(d)Uterus

Answer 1

It is a muscular tissue present at the lower part of the abdomen. It stores urine and helps in the excretion of urine to the outside. In males, it also helps in the ejaculation of the sperms.

Complete answer:
The key male reproductive organs include the testes, epididymis, urethra, vas deferens, prostate gland, seminal vesicle, and penis. Inside each testis are seminiferous tubules, the walls of it produce the sperm by a process called spermatogenesis. Between these tubules are special cells known as Leydig cells or interstitial cells, they secrete the male sex hormone testosterone. From the testis, the sperms are collected by 10-20 vasa efferentia and are transported to the epididymis. The epidermis is a highly coiled tube, about 6m long, sperm concentration and maturation occur within this tube. A straight tube arises from the base of epididymis called the vas deferens, about 40 cm long which carries sperms to the urethra. Most of the sperms are stored in the vas deferens. Another tube urethra carries sperms from the vasa-efferentia and urine from the urinary bladder through the penis.

Additional Information:
-The male reproductive is composed of a pair of testes, genital ducts, accessory glands, and the penis. The two testes are the male gonads, where the male gametes or sperms are made. -Each testis is an ovoid body measuring about 5cm in length, 2cm in breadth, and 3cm in height and weigh about 5 to 7 grams.
-The testicular wall is composed of a fibrous coat called tunica albuginea. Wall-like partitions divide the interior of the testis into about 250 small compartments known as lobules. Each lobule contains about two to three seminiferous tubules.
So, the correct answer is 'Urethra'.

So, the correct answer is 'Urethra'.

Note:
-The testes produce the male sex hormone testosterone. The testes are situated in the scrotal sacs. The scrotum is a thin loose sac of skin underneath the penis that is sparsely covered with pubic hair and contains the testicles.
-The scrotum has a layer of muscle fibers that contract involuntarily as a result of sexual stimulations, exercise, exposure to cold, causing the testes to be drawn up against the body.
-In hot weather, the scrotum relaxes and allows the testes to hang more freely away from the body, outside the abdominal cavity.
