Transcript Hormonal Response to Stress

Hormonal Response to Stress
Adrenal Glands



located above
each kidney
inner adrenal
medulla
outer adrenal
cortex
Adrenal Medulla hormones



epinephrine (adrenaline) and
norepinephrine (noradrenaline) produced
during times of stress
released into blood, causes glycogen to
be converted to glucose, sugar levels
speeds up heart & breathing rates, cell
metabolism, and causes pupil to dilate
(more light into retina)
Adrenal Cortex hormones


glucocorticoids – ex cortisol. Helps
body recover from stress.
mineralocorticoids – ex aldosterone.
Helps kidneys maintain fluid levels.
Short-term Stress Response
Results In:
in blood glucose
b/c glycogen
converted
in HR, BR & cell
meta.
More blood flow to
heart and muscle
cells
epinephrine &
norephrine secreted

Long-term Stress Response
Mineralcortocoids:


in Na+ & H2O retained
by kidneys
in blood volume & pres.
Glucocorticoids:

in blood glucose levels
(proteins & fats convert.)

suppression of immune
system
cortisols
