Quizplus · Accepted Answer

Catecholamines (such as adrenaline and noradrenaline) interact directly with sympathetic receptors throughout the body, which is why they are often referred to as "fight or flight" hormones. This interaction triggers a variety of physiological responses, including increased heart rate and blood pressure, dilation of the airways in the lungs, and increased glucose release from the liver.
