Male Reproductive Systems
| Term | Definition |
|---|---|
| Urinary Bladder | A muscular organ that acts as a reservoir for urine. |
| Seminal Vesicle | Glands about 2 in. long that attach to the vas deferens near the base of the bladder. They produce fluid that mixes with the sperm to make them more mobile and to provide nourishment. |
| Testes | The male sex glands. They manufacture the male hormone testosterone and produce sperm. |
| Scrotum | The sac that hangs outside the male body and holds the testes. Keeps the testes at the right temp (just under 98.6 degrees) so the testes can produce sperm. |
| Epididymis | The highly coiled structure located on the back side of each testis. Stores newly produced sperm. |
| Penis | The penis is a tubelike organ that functions in sexual reproduction, sexual pleasure, and elimination of liquid body waste. |
| Vas Deferens | The vas deferens are a long tube which connects the epididymis to the urethra. |
| Prostate Gland | The prostate gland lies just below the bladder and surrounds the urethra. It secretes a milky, alkaline fluid that mixes with the sperm and makes up the major portion of semen. |
| Cowper's Gland | Two pea sized glands just below the prostate which opens into the urethra. They secrete a clear, sticky fluid that is thought to cleanse the urethra of acid from urine allowing safe passage for sperm. |
| Urethra | A tubelike organ that travels through the penis. It serves as a passageway for semen and urine. When semen is preparing to leave the body, muscles contract and close off the bladder, therefore no urine will be released during ejaculation. |
