Final answer:
Cortisol enhances catecholamines, which are hormones that promote the body's fight-or-flight response to stress. This interaction is an example of the body's stress response.
Step-by-step explanation:
When presented with a stressful situation, the body responds by releasing hormones called catecholamines, which include epinephrine and norepinephrine. These hormones enhance and extend the body's fight-or-flight response by increasing heart rate, force of contraction, and blood flow to vital organs. Cortisol, a steroid hormone released in prolonged stress, enhances the effects of catecholamines by promoting the breakdown of stored nutrients for energy and inhibiting tissue building. This interaction between cortisol and catecholamines is an example of how the body responds to stress.
