Andre45 [30]

Answer;

Adrenal glands

Explanation;

​-When confronted with a stressor, the adrenal glands respond by producing stress hormones, including catecholamines, cortisol, and epinephrine.

-In response to acute stress, the body's sympathetic nervous system is activated due to the sudden release of hormones. The sympathetic nervous systems stimulate the adrenal glands triggering the release of catecholamines, which include adrenaline and noradrenaline.

-These "stress hormones" cause several changes in the body, including an increase in heart rate and blood pressure.
