Sperm – the sex cells that are made by males and that are needed to fertilize eggs.
Testes – the male reproductive organs that produce sperm and testosterone.

Scrotum – the skin covered sac that surrounds the testes.
Epididymis – once sperm are made
they move into this coiled tube. Vas Deferens –
once a sperm matures, it travels into this tube.

Semen – sperm and the added fluids.
Urethra - the tube that passes through the penis. Sperm leave the body during ejaculation via this tube.
Prostate Gland – the male gland that adds fluid to the sperm to nourish and protect it.

Eggs - the sex cells of females that can be fertilized by sperm.
Ovaries – the female
reproductive organs that
produce eggs and
hormones.
![Page 23: Male and Female Reproductive Systems](https://reader033.fdocuments.us/reader033/viewer/2022061605/56813b92550346895da4c15d/html5/thumbnails/23.jpg)
Fallopian Tubes – connect the ovaries to the uterus.
Uterus – the muscular organ the size of a fist where fertilized eggs develop.
Cervix - the narrow base of the uterus.
![Page 24: Male and Female Reproductive Systems](https://reader033.fdocuments.us/reader033/viewer/2022061605/56813b92550346895da4c15d/html5/thumbnails/24.jpg)
Endometrium – the lining of the uterus that thickens as an egg matures.
Placenta - a blood vessel-rich tissue that forms in a mother’s uterus.
Vagina - reproductive organ that connects the uterus to the outside of the body.
![Page 25: Male and Female Reproductive Systems](https://reader033.fdocuments.us/reader033/viewer/2022061605/56813b92550346895da4c15d/html5/thumbnails/25.jpg)

If an egg is not fertilized, the blood vessels in the endometrium break
down. The process in which the blood and
tissue that built up in the uterus flows out of the body through the vagina.

a monthly series of hormone-controlled
changes that mature an egg and prepare the uterus
for pregnancy.
