2 A) Structure The female gonads are the ___________ Their main function is to _________________Mature egg cell of the female is called an ovum
3 fallopian tube—a passageway from the ovaries to the uterus uterus—hollow muscular organ in which development of the embryo will occur (if fertilization occurs)during sexual intercourse, sperm are deposited into the vaginavagina leads from the outside of the females body to the entrance of the uterus—cervix
5 B) FunctionThe functions of the female reproductive system are to produce eggs and nourish the embryo is the egg is fertilizedEach ovary contains 400,000 follicles—clusters of cells that surround a single egg to help it matureOnly about 400 mature eggs will be released during the life of a woman
6 C) Menstrual Cycle Occurs about every 28 days Regulated by hormones Begins during puberty and ends between the ages of 45-55Menopause: the permanent stopping of the menstrual cycleDuring the menstrual cycle, an egg develops and is released from the ovary while the uterus prepares itself for a fertilized egg
7 Menstrual Cycle: cycle during which an egg develops and is released from an ovary and the uterus is prepared to receive the fertilized eggIf the egg is fertilized, it is implanted in the uterus for development to occur.If the egg is not fertilized, it is discharged with the lining of the uterus
9 Hormones FSH – Released by Anterior Pituitary LH – Released by Anterior PituitaryEstrogen – Produced by the ovary/follicleThickens uterine wall and keeps FSH and LH levels lowProgesterone – Produced by the corpus luteumStimulates blood flow to uterus
10 1. Menstruation This process begins the cycle The tissue, blood and unfertilized egg are discharged through the vagina.Menstruation usually lasts about 3-7 days
12 2. Follicular PhaseThe Follicular Phase is when the follicle that surrounds the egg, as well as the egg, grows and matures.It begins when levels of estrogen are lowFSH and LH are secreted (released) which is what causes the follicle to grow.
13 As the follicle develops, estrogen is produced. The estrogen causes the lining of the uterus to thicken.
