Prepares for fight, flight, fright, or freeze.
Increase respiratory rate.
Increase heart rate, increase respiratory rate, relax smooth muscles of the bladder and GI tract. Blood pressure and glucose.
What hormones are produced in the Adrenal Cortex?
Mineralcorticoids- aldosterone

Blood and Lymph
Androgens, DHEA (sex hormones) targets which organ?
Reproductive organs
What is the function of Aldosterone (mineralcorticoids) in the blood?
Regulates sodium/water balance; long-term regulation of blood pressure.
All adrenal cortex hormones originally derive from cholesterol.
