Reproductive SystemMrs. Wharton’s Science Class

Sexual ReproductionInvolves the production of eggs be the female

and sperm by the male. The egg and sperm join together during fertilization

Zygote- a fertilized egg

Male Reproductive SystemSpecialized to produce sperm and the

hormone testosterone.

The structures include the testes, scrotum, and penis

Testes-Where sperm is producedScrotum-where testes are locatedTestosterone-male hormone which controls

the development of male characteristics

Male Reproductive SystemSperm mixes with fluids.

Sperm-contains the DNA to create new lifeSemen-The mix of sperm cells and fluidsPenis-Semen leaves the body through this

organ

Female Reproductive SystemTo produce eggs and if the egg is fertilized , to

nourish a developing baby until birthThe organs of the female reproductive system

include the ovaries, fallopian tubes, uterus and vagina.

Ovaries- located slightly below the waist on

both sides- produce egg cells and hormonesEstrogen- female hormone triggers

develoopment of female characteristics

VocabularyFallopian Tube- passageways for eggsUterus- or womb, a hollow muscular organ. Once the

egg has been fertilized, it stays in the uterus and develops.

Vagina-muscular passageway leading to the outside of the body

Menstrual Cycle-a monthly cycle of changes that occur in the female reproductive system

Ovulation- when a mature egg is released form the ovary down the fallopian tube.

Menstrual CycleDuring the menstrual cycle an egg develops in

an ovary. At the same time the uterus prepares for the arrival of an embryo.

At the start of the menstrual cycle, the egg starts to mature and the uterine lining starts to thicken. If not fertilized, the lining and uterus and the egg start to break down. The extra blood and tissue pass out of the body through the vagina. This is called menstration.
