OVARIESThe female gonads or sex glands They develop and expel an ovum each monthA woman is born with approximately 400,000

immature eggs called folliclesDuring a lifetime a woman release @ 400 to

500 fully matured eggs for fertilizationThe follicles in the ovaries produce the female

sex hormones, progesterone and estrogenThese hormones prepare the uterus for

implantation of the fertilized egg

FALLOPIAN TUBESServe as a pathway for the ovum to the

uterusAre the site of fertilization by the male

spermOften referred to as the oviducts or

uterine tubesFertilized egg takes approximately 6 to

10 days to travel through the fallopian tube to implant in the uterine lining

MENSTRUATION Menarch, the onset of

menstruation signals the bodily changes that transform a female body

Average age is 12.8 Amount of bleeding

varies from woman to woman

Expulsion of blood clots

Blood color can vary from bright red to dark maroon

Usually occurs every 25 to 32 days

Women can experience fluid retention, cramping, mood swings, weight gain, breast tenderness, diarrhea, and constipation

BREASTS Organs of sexual arousal Contain mammary glands Consist of connective tissue

that serves as support Each breast contain 15-25

clusters called lobes Each lobule is connected by

ducts that open into the nipples

The nipples are made up of erectile tissue

The pigmented around the nipples are called the areola

Breast size is determined primarily by heredity

Size also depends on the existing fat and glandular tissue

Breasts may exhibit cyclical changes, including increased swelling and tenderness prior to

menstruation Benign breast changes

refer to fibrocystic disease Lumps or masses that are

noncancerous

BREAST SELF-EXAMINATIONWomen need to examine their breasts

monthly BSEThis is a proactive approach to detect

possible breast cancerA supplement to clinical exams and

mammographyBest time for a BSE is a week after

menstruation
