Which chemicals are primarily released during the fight or flight response?

Serotonin and dopamine
Insulin and glucagon
Adrenaline and cortisol
Testosterone and estrogen

The correct answer is: Adrenaline and cortisol

During the fight or flight response, the body undergoes a series of physiological changes that are critical for survival. The chemicals primarily involved in this response are adrenaline (also known as epinephrine) and cortisol. Adrenaline is released from the adrenal glands in response to stress. It enhances your heart rate, increases blood flow to muscles, and elevates blood pressure, effectively preparing the body to either confront or escape from a perceived threat. Cortisol, a glucocorticoid steroid hormone, also plays a significant role by regulating various bodily functions, including metabolism and the immune response, and it assists in managing stress levels over a longer duration. Together, these hormones enable a swift response to danger, ensuring that the body is adequately prepared to either fight off an aggressor or flee from a stressful situation. The other options, while they involve important bodily functions, do not directly pertain to the immediate hormonal responses associated with the fight or flight mechanism.
