Answer Details
The part in the mammalian male reproductive system that serves as a passage for both urine and semen is the urethra. The urethra is a tube-like structure that connects the urinary bladder to the outside of the body. In males, the urethra passes through the penis and serves as a passage for both urine and semen.
During urination, urine travels from the bladder and out through the urethra to be expelled from the body. During ejaculation, semen (which contains sperm and other fluids) travels from the testes and out through the urethra to be expelled from the body. The urethra has a valve-like structure that prevents urine and semen from being expelled at the same time, ensuring that each fluid is expelled separately.
Overall, the urethra is an important part of the male reproductive system as it serves as a common passage for both urine and semen to exit the body.
