3.9a Male Reproductive System



1. Bladder at the top - Stores urine
2. 2 testis - Carry out the process of meiosis - produces the gamete known as sperm cells
3. Sperm cells are stored in the epididymis
4. The tube from the testis is called the vas deferens - (contracts to move sperm to penis)
5. As the sperm cells move they pass the prostate - This adds 20 - 30% of the volume of semen - containing sugars and being alkaline - neutralize acidic secretions within the vagina
6. The seminal vesicles produce sugar based secretions - alkaline 70% of semen
7 Sperm cells + prostate + seminal vesicles = semen
8. Common tube = the urethra - common tube
9. Urethra carries semen and urine
10. Penis - carries sperm cells into vagina during intercourse
