Science W1A - Male Reproductive System Flashcards
All living things, like human beings, are able to to breed offspring through this process.

Role of Male Reproductive System
to produce and transport sperm cells
It is a tube that passes through the penis to the outside of the body which carries urine and sperm.
urethra
a soft, tubular organ that hangs front of the body and is the external sexual organ of the male through which the sperm are delivered into the female’s body
penis
are made up of coiled tubules in which the sperm are produced
testes
a coiled J-shaped tube located on the back of each testicles.
epididymis
stores the sperm after they have been produced
epididymis
a tube that receives sperm from the epididymis of each testicle
vas deferens
a pouch of skin that hangs from the penis which houses the testes and it protects the sperm by keeping the temperature of the testes slightly lower than normal body temperature
scrotum
produces a fluid rich in sugars that sperm cells use for energy
seminal vesicles
transports sperm and seminal fluids to the urethra during ejaculation
ejaculatory ducts
produces alkaline fluid that neutralizes the acids present in the female reproductive system
prostate gland
produces alkaline fluid that neutralizes traces of acidic urine in the urethra
bulbourethral gland
ducts of the male reproductive system
urethra, vas deferens, ejaculatory ducts
glands of the male reproductive system
seminal vesicles, prostate gland, bulbourethral gland
located in the testes and fertilizes the egg
sperm cell
It is produced by the Leydig cells. (Found between the seminiferous tubules) It regulates the development of the male sex organs in embryo. It also controls sex drive and secondary sex characteristics at puberty.
testosterone (gland: testes)
stimulates sperm and testosterone production
luteinizing hormone (gland: pituitary)
stimulates sperm production in the seminiferous tubules
follicle-stimulating hormone (gland: pituitary)
