body fluid osmolarity
300mOsm
Tm is
transport maximum
nearnst equation shows
the equilibrium potential for a substance

function of insulin
lowers glucose via blood uptake and activating liver enzymes
increases insulin..
high glucose
parasympathetics
glucagon
GIP
decreases insulin
low glucose
sympathetics
type one diabetics defect
beta cells in islets of langerhans
glucagon occurs in which state
hungry
glucagon raises glucose via
glycogenolysis
gluconeogenesis
lipolysis
glucagon increased by
low glucose
sympathetics
glucagon decreased by
high glucose
high insulin
adrenalin functions
increase glucose
increases gluconeogenesis
increases glyconolysis
cortisol functions
increases glucose and lipolysis
where is growth hormone released
anterior lobe of pituitary gland
growth hormone functions
decrease muscle glucose uptake
increase glucose from liver
increase lipolysis
carotid sinus baroreceptor nerve
glossopharyngeal
aortic arch baroreceptor nerve
vagus
synapse of baroreceptor nerve endings
nucleus tractus solitarus
cardiovascular centre location
low pons
increase HR and contractility
sympathetics
high pressure - nerve innervation:
parasympathetic
parasympathetic vascular effects
dilate veins and arteries
low TPR and low CO
sympathetic effects
vessel constrion
high TPR and CO
high BP
