write in question answer form Imagine your car is totaled in an accident and you need to drain your savings account to make repairs. This might make you unable to meet goals such as taking a vacation or making a down payment on a new home. Likewise, when your body is affected by an adverse incident, such as injury or infection, its resources are drained, and normal function becomes limited. When the circulatory system is unable to supply an adequate amount of oxygen and nutrients to the cells to meet the body's metabolic requirements, a life-threatening condition called shock occurs. A series of compensatory mechanisms will attempt to improve the distribution of oxygen, but if the body can no longer compensate, cell death will occur. Shock has distinct stages: compensated, progressive, and irreversible. During the compensated, or preshock stage, the body will increase blood pressure by releasing catecholamines and hormones. Often with hypovolemic shock, pulse pressure will narrow. Chemical compensation will stimulate chemoreceptors to increase the circulating oxygen levels with hyperventilation. If shock is not aggressively treated during the compensated stage, it will advance to the progressive stage, where the compensatory mechanisms begin to fail. In the final, irreversible or end-organ dysfunction stage, cell death occurs from anaerobic metabolism, which leads to irreversible organ failure. Different types of shock manifest with different symptoms. Hypovolemic shoc
