Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which hormone is secreted by the adrenal glands (adrenal medulla); and the function intensifies stress and triggers the body’s “fight-or-flight” response, causing increased heart rate, blood pressure, and respiration?
A
cortisol
B
luteinizing hormone (LH)
C
epinephrine (adrenaline)
D
aldosterone
Explanation: 

Detailed explanation-1: -Adrenaline is produced in the adrenal glands, which release adrenaline into the body during times of stress or danger. It prepares your body to face a stressful “fight or flight” situation.

Detailed explanation-2: -The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.

Detailed explanation-3: -The adrenal cortex produces several hormones. The most important are aldosterone (a mineralocorticoid), cortisol (a glucocorticoid), and androgens and estrogen (sex hormones). Aldosterone helps the kidneys control the amount of salt in the blood and tissues of the body.

Detailed explanation-4: -The adrenal medulla secretes catecholamines, hormones that help your body respond to stress. Catecholamines include adrenaline and noradrenaline, also known as epinephrine and norepinephrine. Within moments, your body releases adrenal medulla hormones to boost organ functioning.

Detailed explanation-5: -Hormones secreted by the adrenal medulla are: Epinephrine: Most people know epinephrine by its other name-adrenaline. This hormone rapidly responds to stress by increasing your heart rate and rushing blood to the muscles and brain.
