Adrenaine is secreled directty into the blood and carmed to diferent parts of the body. The target avgans or the specfic tissues on which it acts include the heart. As a result, the heart beats faster resuting 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 artenies 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 Al these responses together enable the animal body to be ready to deal with the situation. Such animal hormones are part of the endocrine system which consttutes a second way of control and coordaination in our body
