endocrine system Flashcards
ADH full form
antidiuretic hormone
ADH purpose
regulates water balance by increasing water reabsorption in the kidneys, reducing urine production
ADH path
pituitary gland -> kidneys
melatonin path
pineal gland -> hypothalamus
insulin/glucagon path
pancreas -> bloodstream
growth hormone releasing hormone path
hypothalamus -> pituitary gland
human growth hormone path
pituitary gland -> bones (growth plates)
thyroid releasing hormone path
hypothalamus -> pituitary gland
thyroid stimulating hormone path
pituitary gland -> thyroid
gonadotropin releasing hormone path
hypothalamus -> pituitary gland
FSH/LH path
pituitary gland -> gonads
testosterones path
testes (male), adrenal gland & ovaries (female) -> body
estrogen path
ovaries (women), testes & adrenal gland (male) -> body
T3/T4 (thyroid) path
thyroid gland -> bloodstream
erythropoietin path
kidneys -> bone
epinephrine path
adrenal gland -> blood & muscles
melatonin purpose
regulates circadian rhythm & influences reproductive hormones
insulin/glucagon purpose
insulin - lowers blood glucose levels by converting it to ATP
glucagon - raises blood glucose levels by stimulating the release of glucose from liver
growth hormone releasing hormone purpose
stimulates release of human growth hormone from pituitary gland, promoting growth & development
human growth hormone purpose
promotes growth, cell repair, and metabolism in tissues (growth plates)
thyroid releasing hormone purpose
stimulates release of thyroid stimulating hormone from pituitary to regulate thyroid activity
thyroid stimulating hormone purpose
stimulates the thyroid gland to produce and release thyroid hormones T3/T4
gonadotropin releasing hormone purpose
stimulates release of fsh/lh from pituitary, regulating reproductive functions
fsh/lh full form
follicle - stimulating hormone & luteinizing hormone
fsh/lh purpose
fsh - stimulates growth of ovarian follicles and sperm production
lh - triggers ovulation and promotes production of testosterone
testosterone purpose
male - sex hormone responsible for development of male reproductive organs & sperm production
female - maintains bone density, muscle mass, and overall energy levels
estrogen purpose
female - sex hormone responsible for development of female reproductive organs & menstrual cycle
male - bone health, cardiovascular function, and reproductive processes
converts testosterone to estrogen
aromatase
T3/T4 purpose
regulates metabolism, energy production, & growth/development in some places
erythropoietin purpose
stimulates production of red blood cells in bone marrow in response to low oxygen levels (erythropoiesis)
epinephrine (adrenaline) purpose
‘fight or flight’ response, raises heart rate, dilates airways, & redirects blood flow to support physical activity in response to stress/danger
