Adrenal medulla enables us to face physical and emotional stress. Still it is not vital for survival. Its removal does not cause death as it simply augment the sympathetic nervous system.
The adrenal glands release adrenaline, the hormone most often associated with the fight or flight response and danger.
Adrenaline, also known as epinephrine. When released, it causes the "flight or fight" response, which includes: increased heart rate, constricted blood vessels, and dilated airways (so as to get more blood and oxygen to the muscles) as well as dilated pupils and increased sweating. It also pauses digestion so that all energy can be focused on the danger at hand.
Adrenal glands. They called so as they lie by by the kidneys - ad+renal. They control a number of functions and famous for their hormone adrenaline - the stress hormone. It is necessary for animals to start muscular reaction to danger (fight of flight), but its excess can be destructive to the person under chronic stress when adrenaline is not utilised.
Several such as cortisol, cortisone, alderstone, epinephrine, norepinephrine, adrenaline, and finally, androgens which consist of androstenedione and DHEA which together are converted to testosterone.
Adrenaline
adrenaline
Hormone which is released from the adrenal glands when danger threatens or in an emergency. When secreted into the bloodstream, it rapidly prepares the body for action in emergency situations. The hormone boosts the supply of oxygen and glucose to the brain and muscles, while suppressing other non-emergency bodily processes.
The adrenal gland releases adrenaline - this works on the lungs and the heart to keep the heart beating at an effective rate - it also keeps the airways to the lungs open. Adrenaline is also released under 'Fight or Flight', when in danger adrenaline allows your body to work much harder for longer to ensure that you don't get eaten by a lion or whatever. If your blood volume is low or your blood pressure too high - the adrenal gland also releases a steroid hormone called aldosterone. This acts on the kidney to moderate the volume of the blood and on vessels around the body to widen them and reduce blood pressure.

The fight-or-flight response is influenced and enhanced by the adrenal system. When an animal senses danger, on-rushing epinephrine springs them into action.
yes it is because your pancreas produces insulin. insulin is a hormone that helps your blood sugar.
the response is made when your in danger or are under extreme stress such as in a fight or when you need an extra boost
