1: When you are faced with stressful situations, cortisol, epinephrine, and norepinephrine are released by your. kidneys.
The pituitary gland, through the release of ACTH (adrenocorticotropic hormone) regulates the release of cortisol from the adrenal glands into the bloodstream. When the body encounters stress (physical or mental) in response to a trauma, cortisol is released, which in turn regulates the body's inflammatory response. Other effects of cortisol release include: 1) Stimulation of the liver to produce carbohydrates; the short-term fuel for the musculature. 2) Temporary elevation of blood glucose levels.
