Stages of GAS: The Resistance Stage The body adapts to the continued presence of the stressor by producing more epinephrine, increasing alertness and blood pressure, and suppressing the immune system
Stages of GAS: The Resistance Stage 2 A new level of homeostasis characterized by increased resistance to stress; the body returns to normal functioning as stress symptoms diminish.
Stages of GAS: The Exhaustion Stage If coping attempts fail, the ability to resist is depleted, stress remains, and the alarm reaction continues for a long time causing life-threatening physiological exhaustion and harmful effects

Coronary Thrombosis A term used to describe the blockage of a coronary artery secondary to blood clotting within the artery
Angia Pectoris Is chest pain, a signal that the heart is not getting enough oxygen to supply its needs
