Oxytocin - what and produced where? (where it starts, and where it goes)
produced in hypothalamus, released from posterior pituitary. targets uterus, contractions, mammary glands - milk
ADH - antidiuretic hormone (vasopressin) - produced where and released from where? Targets what? (hypo has adhd)
produced in hypothalamus, released from posterior pituitary. targets kidneys and blood vessels, increases water retention.
pineal gland - hormone
hormone - melatonin. targets brain - waking and sleeping
thyroid gland - what hormones and what do they target? (toned bc no milk)
hormones - T3, T4, calcitonin. T3 and T4 - targets most cells. calcitonin - targets bones and kidneys, lowers blood calcium
parathyroid - what hormone and targets what? (parrot crushing)
hormone - PTH, targets bones and kidneys, raises blood calcium
thymus - what hormone and targets what? - Stimulates production of what?
hormone - thymosin - targets lymphatic tissues, stimulates production of T cells
insulin - where and targets what? (insulin - muy MAL)
pancreas hormones (abdomen) - targets liver, muscle, adipose, decreases blood glucose
glucagon - where and targets what?
pancreas hormones (abdomen) - targets the liver, increases blood glucose
GHIH - (gigi)
(somatostatin). made in pancreas and hypothalamus, gi tract - inhibits secretion of insulin and glucagon
adrenal medulla - which hormones, and targets what?
epinephrine and norepinephrine. targets heart, blood vessels, liver, and lungs. increases heart rate, blood sugar (fight or flight)
adrenal cortex - hormones
mineralcorticoids, glucocoricoids, androgens
mineralcorticoids - targets what and does what?
THIS IS (aldosterone) - target the kidneys, increase retention of Na+ and excretion of K+.
More salt - more fluid, raises bp
glucocorticoids
targets most tissue, released in response to long-term stressor, increase blood glucose.
cortisol is a glucocorticoid
androgens (andro)
targets most tissue, stimulates development of secondary sex characteristics
GI tract hormones (3 gi)
gastrin, secretin, CCK (cholecystokinin)
gastrin (gastric acid) - stimulates the release of what and produced where?
produced by G cells in stomach. targets stomach, stimulates release of HCl
secretin (maggie cooking) targets what?
released by duodenum. targets pancreas and liver. stimulates release of digestive enzymes and bile
CCK - cholecystokinin
released by duodenum - targets pancreas and liver, stimulates the release of digestive enzymes and bile
kidneys - hormones
erythropoietin and calcitriol.
erythro - bone marrow, stimulates production of new RBCs,
calcitriol - form of vitamin D3. Vitamin D helps your body absorb calcium from the stomach
heart hormones - what do they do?
ANP - atrial natriuretic peptide - targets kidneys and adrenal cortex. reduces reabsorption of Na+, lowers blood pressure
adipose tissue hormones - and what do they do?
leptin - targets brain, suppresses appetite.
hormones produced in the ovaries - (ovary pie)
estrogen, progesterone, inhibin.
estrogen - targets what? (estrogen BOUM)
targets uterus, ovaries, mammary, brain. secondary sex characteristics
progesterone (pro preg)

urinary system (3)
kidneys, urinary ducts and bladder
3 layers of kidneys
renal cortex (outer), renal medulla and renal pelvis
renal cortex (mattias w/ glum and hat)
outer layer of kidneys where blood vessels are located - composed of one million nephrons which have clusters of capillaries called glomerulus, surrounded by bowman’s capsule, leads to tubule
renal arteries (from a to a to a - then glum)
branch off the aorta, blood flows from arteries to arterioles in glomerulus, then filtered.
glomerular filtrate (glom WIG)
enters proximal convoluted tubule where water, ions, glucose and other molecules reabsorb into bloodstream
distal convoluted tubule (distal denver and ph)
removes urea and drugs. ph can also be adjusted here by secretion of hydrogen ions
unabsorbed material leaves…
collecting tubules in renal medulla and goes to renal pelvis as urine.
