-where urine passes thru
Epididymus
-from testes sperm go here
-it is a tightly coiled tube where sperm mature and are stored
-then they go to the vas deferens
Vas Deferens
-Long tube
-as they trael through here, they mix with a fluid and become semen
Seminal vesicle
- Found near the base of the urinary bladder
-they produce nourishment for the sperm and help them move
Prostate gland
-encircles the uethra near the bladder
-secretes a thin, milky fluid that protects the sperm from acid in the female
Bulbourethral Glands
-found below the prostate
-secretes a fluid that protects the sperm from acid in the male
Ovaries
-female orga that produces eggs and the hormones, estrogen and progesterone
Vagina
-connects the outside of the body to the uterus
-recieves te sperm
-allows menstrual flow to leave the body
Urethra

- meets the vagina at the lower end called the cervix
Ovulation
-the release of an egg from a follicle in an ovary
Pap smear
-examines teh cells of te cervix
-importnt for preventing cervicle cancer
Fertilization
-from the vagina, sperm travel thru the uterus and falopian tubes where fertilization occurs
-one sperm penetrates the egg and they join to form a zygote
Zygote
-zygote travels down the fallopian tube towards teh uterus
-takes about 3-5 days
As the zygote moves down the tube, the cell divides into 2, and then into 4..ect
Embryo
-first 8 weeks and embryo stage
- the embryo travels from the fallopian tube to the uterus
Placenta
- ablood vessel rich organ that forms in a mother's uterus and that provides nutrients and oxygen and removes waste
First trimester
-first three months
-heart starts beating
leg and arm buds
-eyes and brain begin to develop

-distinctly male or female
-hair, head, facial features
-fingers and toes grow nails
Third trimester
-months 7-9
-when fetus gains most of its wait
-
Dialation
-first stage of child birth
-the uterus contracts which causes the cervix to open up
-"water breaks"
-ends when cervix is opened 10 cm
Expulsion
-second stage
-the head emerges fullyand the shoulders rotate
-an episotomy may be done (cutting the vagina for more room)
- ends with the delivery of teh baby
