One such example of the endocrine gland is the Adrenal gland situated just above the kidney and it secretes adrenaline. It is released in case of an emotional, dangerous, stressful situation. The main role of this hormone is to prepare the body for flight and fight. Whenever there is any danger, trauma or emotional stress, the release of the adrenaline is triggered which fills your body with energy so as to fight in an emergency situation. After the effect of adrenaline is finished, the body calms down, the blood sugar gets lowered and the normal physiology is attained.

Adrenaline is known as fight or flight hormone.

Adrenaline dilates the pupil, increases or lowers the blood sugar or heart rate during the time of stress. It also controls respiratory movements.
