Reproductive System- Natalia Hernandez
Hormones
Testosterone
Stimulates reproducing organ development and sex drive: causes secondary sex characteristics
Inhibin
release by testes when high levels of testosterone are present
Gonadotropin Releasing Hormone (GnRH)
releases LH and FSH
Estrogen
primary female sex hormone released by follicle (female)
Follicle Stimulating Hormone (FSH)
stimulates stimulates sertoli cells for sperm production and maturation and inhibin
Progesterone
triggers suppression of the hypothalamus for releasing GnRH: stimulates the development of lining in uterine, mammary glands for lactation (in females)
Luteinizing Hormone (LH)
stimulates seminiferous tubules to secrete testosterone ( in Males)
Reproductive System:
Asexual Reproduction
Single parent produces genetically identical off spring.
Sexual Reproduction
two gametes (female and male) offspring is genetically varied
gonads: produce gametes (sex cells)
Secrete Hormones
Female
Organs
Uterus
receives fertile egg, retains, and nourishes
Vagina
serves as birth canal
Uterine tube
receives ovulates oocyte
ovaries
Female gonad
Male
Organs
Sperm
male gamete
Epididymis
mature and store sperm
Testes
primary sex organ
ductus deferens
carries sperm from epididymis yo ejaculatory duct
Urethra
carries birth sperm and urine
Seminal Vesicle
contains fructose to nourish and activate sperm
Prostate Gland
secretes milky white fluid activates sperm
Bulbourethral Gland
lubricates penis by secreting alkaline mucus
Hormonal Cycle
Ovarian Cycle
Ovulation
triggered by sudden spike increase
in LH caused by steady increase in estrogen stimulating thepituitary glang
Luteal Phase
Follicle expels oocyte and the epmty shell becomes corpus luteum
Follicular Phase
Follicular cells secrete estrogen to become secondary follicle
Menstrual
Proliferative Phase
estrogen stimulated growth: causing double thickness
Menstruation
decline in estrogen and progesterone causing arteries to constrict cells become ischemic and die: shed by bleeding
Secretory Phase
uterine glans enlarge and secret nutients
Menopause
menstrual cycle ceases.
diseases
prostate cancer
2nd most common in men
