GENERAL HISTOLOGY

Detailed explanation-1: -When the erect penis is stimulated, muscles around the reproductive organs contract and force the semen through the duct system and urethra. Semen is pushed out of the male’s body through his urethra-this process is called ejaculation.

Detailed explanation-2: -When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder.

Detailed explanation-3: -Urethra. This is a tube that allows urine to flow outside the body. It is also the channel for semen to pass during ejaculation. The brain signals the bladder muscles to tighten.

Detailed explanation-4: -Sperm cells pass through a series of ducts to reach the outside of the body. After they leave the testes, the sperm passes through the epididymis, ductus deferens, ejaculatory duct, and urethra.
