reproductive system elizabeth gomez-barajas 2 period
anatomy of the male structures
epididymis
prostate
testis
ejaculatory duct
prepuce (foreskin)
seminal gland (vesicle)
corpora cavernosa
bulb of penis
urethra
ductus deferens
events of the female hormonal cycle
follicular phase
starts the first day of your period, lasts for 13 to 14 days ending in ovulation
ovulation
day 14, when a mature egg is released from an ovary and moves along the fallopian tube towards the uterus
menstrual phase
happens once a month, usually every 28 to 30 days, lasts 3 to 7 days
luteal phase
begins around day 15 of a 28-day cycle and ends when you get your period
methods and classification of contraceptives
coitus interruptus
chemical barriers
contain spermicides
combined hormone contraceptives
contain estrogen and progestins to prevent pregnancy
mechanical barriers
prevent sperm from entering vagina during sexual intercourse
rhythm method
abstinence from sexual intercourse around time of ovulation
injectable contraception
intrauterine devices (IUDs)
implanted in the uterus
sterilization
surgical method of permanently preventing pregnancy; vasectomy for male, tubal ligation in female
contraceptive implants
implant in arm contain progestin
hormones of the reproductive system
female
estrogen
responsible for female secondary sexual characteristics : breast development, sex organ enlargement, increased adipose tissue deposition, increased vascularization of the skin
progesterone
triggers uterine change during menstrual cycle
male
androgens
male sex hormones; testosterone is the most important one
actions of testosterone
stimulates development of male reproductive organs
responsible for male secondary sexual characteristic : deep voice, body hair, thickening of hair, increased muscular and skeletal growth
major functions of the reproductive system
female
labia majora
enclose and protect other external reproductive organs
labia minora
form margins of vestibule ; protect openings of vagina and urethra
vagina
conveys uterus secretions to outside of body; provides a passage way for offspring during birth process
clitoris
produces feelings of pleasure during sexual stimulation due to abundant sensory nerve ending in glans
uterus
protects and sustains embryo during pregnancy
vestibule
space between labia minora that contains vaginal and urethral opening
uterine tube
conveys secondary oocyte towards uterus ; site of fertilization ; conveys developing embryo to uterus
vestibular glands
secrete fluid that moistens and lubricates vestibule
ovary
produces oocytes and female sex hormone
male
seminal vesicle
secretes an alkaline fluid containing nutrients and prostaglandis that help regulate PH of semen
prostate gland
secretes fluid that contains citrate, a nutrient for sperm
ductus deferens
conveys sperm cells to ejaculatory duct
bulbourethreal gland
secretes fluid that lubricates end of penis
epididymis
promotes sperm cell maturation ; stores sperm cells ; conveys sperm cells to ductus deferens
scrotum
encloses, protects, and regulates temperature of testes
testis
seminiferous tubules
produce sperm cells
interstitial cells
produce and secrete male sex hormones
penis
conveys urine and semen to outside of body
anatomy of the female structures
posterior fornix
fimbrae
perimetrium
ampulla
myometrium
lumen of uterus
endometrium
body of uterus
labium majus
labium minus
lemun of vagina
cervix
uterus
vagina
ovary
infundibulum
uterine tube
disorders associated with the reproductive system
genital herpes
genital sores, fever
antiviral drug (acylovir)
herpes simplex 2 virus (HSV2)
genital warts
warts on genital
chemical or surgical removal
human papilloma virus (HPV)
chlamydia infection
painful urination and intercourse, mucous discharge from penis or vagina
antibiotics
chlamydia trachomatis bacteria
gonorrhea
in women, usually none in men, painful urination
antibiotics
neisseria gonorrhoea bacteria
acquired immune deficiency syndrome (AIDS)
fever, weakness, infections, cancer
drugs to treat or delay symptoms
human immunodeficiency virus (HIV)
syphilis
chancre usually in genitals or mouth: rash six months later; several years no symptoms, infections spreads to liver,nerves, and brain
antibiotics
treponema pallidum bacteria
