Which of the following forms a common passage for both the sperms and urine in males?
Scrotum
Urethra
Urinary bladder
Vas deferens
Urethra
The urethra is the common duct that serves as the exit pathway for both urine from the urinary bladder and semen from the reproductive system in males. It extends from the neck of the bladder through the penis to the external urethral orifice.
The urethra is the common duct that serves as the exit pathway for both urine from the urinary bladder and semen from the reproductive system in males. It extends from the neck of the bladder through the penis to the external urethral orifice.
Think of the urethra as a multi-purpose tunnel or a 'shared driveway' that leads from a house (the bladder) and a garage (the reproductive glands), both of which use the same exit route to get to the main road.
Urethra: 'U' for 'U'rine and 'U'nified (shared) path.
N/A тАФ This is a biological anatomical structure.
During the micturition reflex, the bladder contracts and the internal sphincter relaxes to allow urine to pass through the urethra. During ejaculation, the reproductive system delivers sperm through the ejaculatory ducts into the urethra; a sphincter at the bladder neck closes during this process to prevent the mixing of urine and semen and to ensure that neither enters the wrong pathway.
The male urethra is approximately 18-20 cm long.
It is divided into three segments: prostatic, membranous, and spongy (penile) urethra.
It is distinct from the vas deferens, which only transports sperm from the epididymis.
Urinary system excretion
Male reproductive system ejaculation
Scrotum: A sac of skin containing the testes, responsible for thermoregulation.
Urinary bladder: A hollow, muscular organ that stores urine.
Vas deferens: A long, muscular tube that travels from the epididymis into the pelvic cavity, transporting mature sperm.
B is correct тАФ The urethra serves as the single anatomical channel that facilitates the passage of both urine and sperm in the male reproductive and urinary systems.
Always differentiate between the roles of the vas deferens (sperm transport only) and the urethra (shared transport). Examiners often test this distinction to check for conceptual clarity on male anatomy.
