Marisa Alberto Period: 3 Lymphatic/Immune System
Events of the hormonal cycle
ovulation- process of releasing the secondary oocyte. Is surrounded by 1 – 2 layers of follicular cells
follicle maturation- secretion from anterior pituitary increases. Development takes about 300 days.
menstrual cycle- characterized by monthly changes in uterine lining
Anatomy of female reproductive structures
uterus- protects and sustains embryo during pregnancy
vagina- conveys uterine secretions to outside of body
uterine tube- conveys secondary oocyte toward uterus
labia minora- form margins of vestibule;
ovary- produces oocytes and female sex hormones
clitoris- it produces feelings of pleasure during sexual stimulation
labia majora- encloses and protects other external reproductive organs
vestibule- space between labia minora
vestibular glands- secrete fluid that moistens and lubricates vestibule
disorders associated with reproductive system
gonorreha- a sexually transmitted diease
heptitis- affected by a viral hepatitis
chlamydia- a common std that can infect both men and woman
trichomoniasis- a very common sexually transmitted disease that is caused by an infection with protzoan parasite
genital herpes- a sexually transmitted diease
aids/hivs- virus that attacks the immune system
syphilis- sexually transmitted infection that can cause serious health problems
hpv/genital warts- sexually transmitted infectiom
PID- a pelvic inflammatory disease
methods and classification of contraceptives
mechanical barriers: prevent sperm from entering vagina during sexual intercourse
rhythm method: abstinence from sexual intercourse around
time of ovulation
chemical barriers: contains spermicides
combined hormone contraceptives: contains estrogen and progestins to prevent pregnancy
contraceptive implants: implantation of a rod containing
progestin under the skin in the arm
IUDs: objects implanted in the uterus
sterilization: surgical methods of permanently preventing
pregnancy
Anatomy of male reproductive structures
ductus deferens: conveys sperm cells to ejaculatory duct
seminal vesicle: secretes an alkaline fluid containing nutrients
epididymis: promotes sperm cell maturation
prostate gland: secretes a fluid that contains citrate
testes: produce hormones and sperm
bulbourethral gland: secretes fluid that lubricates end of penis
scrotum: encloses, protects, and regulates temperature of testes
penis: conveys urine and semen to outside of body
Major funcions of the Reproductive System:
it develops and maintains organs for production of offsprings
male system deliver to sperm to female
produces sex cell and hormones
female system nourishes the developing embryo and fetus
Hormones of the reproductive system
corpus luteum: secretes estrogen and progesterone
progesterone- causes endometrium to become more vascular
estrogens: promote development of female secondary sexual characteristics as a female matures
FSH- stimulates the maturation of a follicle in the ovary
LH- stimulates cells to produce testosterone precursors
GnRH- secretion from the hypothalamus
