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 |
Fight-or-Flight Responses Singes | Elevated heart rate, elevated blood pressure, constricted blood vessels, dilated pupils, alert and aroused state, liberation of glucose and fatty acids for quick energy, body perspires and muscles tighten |

Risk factors for CVD: Can NOT be changed | Heredity (multiple genes contribute to risk), aging (risk goes up), being male, ethnicity (african americans higher risk of hypertension and stroke) |
Forms of heart disease | Heart Attacks, Myocardial infraction (MI), coronary thrombosis, angina pectoris, arrhythmia, sudden death |
Heart Attack | Is a damage to, or death of, heart muscle, sometimes resulting in failure of the heart to deliver enough blood with oxygen to the body; also known as myocardial infraction (MI) |
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 |
Arrhythmia | A condition when electrical impulses that control heartbeat become disrupted, resulting in an irregular pattern |
Sudden Cardiac Death | Cardiac arrest is caused by arrhythmias and ann result in death, if not treated immediately |
