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
