When someone is in danger or in emergency then adrenal gland secrete adrenaline hormone. 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.

Solution 2

An increase in the amount of adrenaline in our body increases our heart beat, breathing rate, blood flow into the muscles and causes the liver to put more stored glucose in our blood. All these actions of adrenaline produces a lot of energy in our body very quickly and enable us to take quick action.
