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.

If more adrenaline is released then the responses would be as follows :
(i) The glucose concentration of the blood would increase as the glycogen will be converted to glucose rapidly.
(ii) The muscles would gain more power due to availability of more glucose.
(iii) The heart beat will increase .
(iv) Thus more blood will be pumped.
(v) Thus the blood supply to muscles would increase .
(vi) The person would have perspiration .
The adrenaline is hence also called the emergency hormone as it helps either to fight danger or to run away from danger.
