What is addison disease? - ANS: hyposecretion of cortisol (adrenal glands are damaged causing a slow production of cortisol) Hypo secretion - ANS: production of a bodily secretion at a very SLOW rate. What hormones do the adrenal glands produce? - ANS: Cortisol & Alderstone Hyper secretion - ANS: excessive production of bodily secretion. (ex. gastric acid, mucus, or growth hormone) What two parts are your adrenal glands composed of? - ANS: 1. Inner medula - produces adrenal - like hormones 2. Outer cortex - produces cortisol Amylase - ANS: Enzyme that converts starch and glycogen into simple sugars. Bile is produced, stored, and released into what organs in the body? - ANS: Produced in the liver, stored in the gall bladder, and released into the small intestine. Cortisol - ANS: A hormone produced by the adrenal glands (cortex). Increases blood sugar during stress and has anti-inflammatory properties.
