Explain the effects of the catecholamines on the body during the fight-or-flight response and how these effects help us deal with short-term stress
What will be an ideal response?
When you feel threatened physically or emotionally, your sympathetic nervous system brings about the "fight-or-flight" response to help you cope with the stressful situation. In response, the adrenal medulla pumps hormones known as catecholamines into the bloodstream to increase heart rate, blood pressure, and the blood glucose level, and dilate the small passageways of the lungs. These events result in more oxygen and glucose in the blood and a faster circulation of blood to the body organs.
