Human phys hormones

insulin

lowers blood glucose by moving glucose in the blood to muscle and adipose cells

glucagon

increases blood glucose by breaking down glycogen and releasing glucose in the blood

epinephrine

increase hr & bp, increase blood glucose to fuel muscle for fight or flight

norepinephrine

fight or flight, increases blood sugar levels

cortisol

stress hormone

erythropoietin

stimulates the production of RBCs which carry O2, increase viscosity, increase heart effort

leptin

satiety signal

neuropeptide Y

increases appetite

ghrelin

increases appetite

growth hormone (GH)

increases musculoskeletal growth

insulin-like growth factors (IGFs)

increases musculoskeletal growth, mediates GH

somatostatin

growth hormone inhibiting hormone

TRH

stimulates anterior pituitary gland to release TSH

TSH

stimulates thyroid gland to release thyroid hormones (T3 & T4)

thyroid hormone

regulate metabolism

growth hormone

musculoskeletal growth/maintenance

vasopressin/ADH

increases water reabsorption, making concentrated urine, which decreases urine volume & prevents dehydration

aldosterone

sodium saver; increases sodium reabsorption by creating Na+ channels; increase of sodium reabsorption increases water retention and blood pressure

atrial natriuretic peptide

sodium excreter; blocks aldosterone - removes Na+ channels; inhibits Na+ reabsorption in kidney leading to a decrease in blood volume & blood pressure

angiotensin II

raises blood pressure by vasoconstricting arterioles, increasing vasopressin release, increasing thirst, increasing aldosterone
