What happens if adrenaline is secreted in large amount in the blood?

Answer 1

When someone is in danger or in emergency then adrenal gland secrete adrenalinehormone. It is secreted directly into the blood and is transported to different parts of the body. It speeds up the heartbeat and hence supplies more oxygen to the muscles. This results in increasing breathing rate and blood pressure which enable them to fight with such urgent situation.

Answer 2

When adrenaline is secreted into the blood it prepares our body for action. It speeds up heart beat and breathing, raises blood pressure and allows more glucose(Carbohydrate) to go into the blood to give us lot of energy quickly to run or fight. And Hence it is an emergency hormone. Additionally it is secreted in the body when body is under severe physical/emotional stress or depression.
