Endocrine Notes - Initials

Pituitary gland - growth hormone Which cells have growth hormone receptors? Bone Cells hormones are signals that have chemicals. inject growth hormones in: people, cows, etc.

thyroid gland - produces hormone that controls energy use (to burn fat) hyper - very high metabolism hypo - low metabolism, instead of using the energy body stores energy (gain wait)

adrenal gland - releases adrenaline hormone adrenaline - raises heart beat, increases blood flow, releases more sugar release when: flight or fight response adrenaline = epinephrine

pancreas - secretes insulin insulin - taking up glucose most cells have insulin receptors

hormones travel through body via the blood signal the body through cells - the receptors (lock) hormone = key (blood) receptor = lock (on the cell)

Urinary System

job of a kidney: clean the blood kidney - filter series of tubes

body is redundant but makes it more likely body will survive

glucose gets filtered into urine through the kindey so small it goes through the urine (urine is sweet - diabetes) don't wanna waste glucose
