    Adrenaline is secreted into the blood stream by adrenal gland in response to cold, joy, anger, fear and emotional stress. The hormone increases the blood supply to heart and skeletal muscles. The small arteries around digestive system and skin constrict thus diverting the blood to our muscles. The breathing rate also increases because of the contractions of diaphragm and the rib muscles. All these responses together enable our body to deal with an emergency situation.
