3.9a Male Reproductive System

recall the structure and the function of the male reproductive system
-bladder- stores urine.
-testis- there is 2 of them- carries out the process of meiosis that produces the gamete called a sperm cell.
-epididymis- stores sperm cells.
-vas deferens- carries the sperm cell to the penis during sexual stimulation. the tube pulses making the walls contract pushing the sperm cells into the penis.
-prostate- adds about 20-30% of the volume of the semen. it contains sugar and is alkali.
-seminal vesicles- produce sugar based secretion, also alkali. 70% of the semen in which the sperm cell can travel.

-when sperm cells are combined with the prostate and the seminal vesicle secretions we have semen- carried forward and down to the urethra (common tube which joins the left and right testes and the left and right vas deferens)

-urethra- takes semen down the penis and the exit for the urine which is stored in the bladder.
-penis- carries sperm cell into the vagina during sexual intercourse.
