| Term | Definition |
| ovary | meiosis occurs producing egg cell, gland that makes estrogen and progesterone |
| ovulation | egg is matured and travels down the fallopian tube (oviduct) |
| fallopian tube | where the egg goes when released, where fertilization takes place |
| egg | female reproductive cell, large with nutrients (23 chromosomes) |
| uterus | where the fertilized egg (zygote) goes to and the zygote develops into a fetus and grows and develops for about nine months |
| cervix | opening through which the baby comes out of; connect uterus to vagina |
| vagina | passageway from uterus to outside; place where penis deposit sperm |
| menstruation | if egg is not fertilized the egg dies, the lining of the uterus comes off and leaves the body, happens once a month, the uterus contracts to push it out, last phase of the menstrual cycle during which the lining of the uterus along with blood and the unfertilized ovum are discharged thourh the vagina |

| liners | outside the vagina to absorb menstruation discharge |
| hymen | membrane that covers the vagina in a newborn, it comes off eventually as girl grows older |
| labia | outer fold of skin outside of vagina |
| clitoris | lots of nerve endings so it is very sensitive |
| scrotum | sack that surrounds the testes to control temperature, so that sperm cells can be produced (lower than body temperature) |
| seminiferous tubules | in the testes, meiosis occurs producing sperm cells, and makes male hormone testosterone |
| sperm | small mobile, produced in large quantities, has tail (23 chromosomes) |
| epididymis | sperm storage area |
| vas deferens | from the testes through the prostate gland, passes through 2 glands that nourish the sperm cells and provide protection |
| semen | fluids that surround sperm cells |
| penis | has erectile tissue that fill with blood |
| prostate gland | produces fluid that helps neutralize the acidity of the vaginal tract; prolonging the lifespan of sperm |
| cowper's gland | produces fluid helps to lubricate the urethra for spermatozoa to pass through |
| seminal vesicles | produces high fructose concentrations provide nutrient energy for the spermatozoa as they travel through the female reproductive system. |
