3.9a - Male Reproductive System


Bladder - Store urine 
Testis - 2 of them - carry out meiosis - produces the gamete, sperm 
epididymis - stored sperm cells 
vas deferens - carry sperm cells to the penis during sexual stimulation. the tube pulses making the walls contract and push the sperm from the testis to the penis
prostate - adds about 20/30% of the volume of the semen. contains sugars and is alkali. 
Seminal Vesicles - 70& of the volume of the semen. contains sugars and is alkali 

When sperm cells are combined with the prostate and seminal vesicles secretions we have semen. - carried forward and down to the urethra 

Urethra - common tube that joins the left and right testis. takes semen/urine down the penis
Penis - carries sperm cells into the vagina during sexual intercourse
