What do some animals experience when they are in a scary situation?

This is done in many animals, using a hormone called adrenaline that is secreted from the adrenal glands.

 

Adrenaline is secreted directly into the blood and carried to different parts of the body. The specific tissues on which it acts include the heart. As a result, the heart beats faster, resulting in supply of more oxygen to our muscles. The blood to the digestive system and skin is reduced due to contraction of muscles around small arteries in these organs. This diverts the blood to our skeletal muscles. The breathing rate also increases because of the contractions of the diaphragm and the rib muscles. All these responses together enable the animal body to be ready to deal with the situation.
