Detailed explanation-1: -The production of adrenaline occurs in the adrenal glands, which sit above the kidneys. Adrenaline is responsible for the fight-or-flight reaction to a threat, and it triggers specific processes in the body. For example, it might make the body send extra oxygen to the lungs to aid a person to run away.
Detailed explanation-2: -Adrenaline is produced in the medulla in the adrenal glands as well as some of the central nervous system’s neurons. Within a couple of minutes during a stressful situation, adrenaline is quickly released into the blood, sending impulses to organs to create a specific response.
Detailed explanation-3: -Adrenal glands produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions. Adrenal glands are composed of two parts-the cortex and the medulla-which are each responsible for producing different hormones.
Detailed explanation-4: -The adrenal gland secretes steroid hormones such as cortisol and aldosterone. It also makes precursors that can be converted to sex steroids (androgen, estrogen). A different part of the adrenal gland makes adrenaline (epinephrine).
