Fallopian Tube �Passageways for eggs as they travel from the ovary to the uterus. �The place where fertilization takes place. �Each month, one of the ovaries release a mature egg, which enters the nearest fallopian tube.
Uterus �A hollow muscular organ about the size of a pear. If an egg is fertilized, it becomes attached to the wall of the uterus. �The cervix is the lower portion of the uterus and is a common site of cancer in women.
Vagina �A muscular passageway leading to the outside of the body. �The vagina or birth canal, is the passageway through which a baby leaves the mothers body.
Ovulation �The process in which an egg is released from the ovaries is called ovulation. �Once it is released, it can be fertilized for the next few days if sperm are present.
Menstruation �When an egg is not fertilized it starts to break down along with the lining of the uterus. �When the extra blood and tissue of the thickened lining pass out of the body through the vagina it is called menstruation. �On average, menstruation last about four to six days.
