Answer:
The adrenal gland secretes the adrenaline hormone into the blood and is carried to various parts of the body. In the event of stress, emergency or any threat, adrenaline is released in larger quantities. This leads to the heart to beat fast, thus causing more of oxygen supply to the muscles. Due to the muscle contraction, the supply of blood to the skin and the digestive system is reduced around the small arteries in these organs. The rate of breathing is also increased as a consequence. These responses collectively assist the animal to deal in case of emergencies.
