Expert Answer
Dear student,
During emergency situations, adrenal gland releases adrenaline hormone which helps in quick actions to deal with the emergency situation. It induces 'fight or flight action' by the body, thereby helping to deal with the situation.
During such emergency situations, adrenal glands release adrenaline into blood which acts on heart and other tissue. This causes faster heart beat, resulting in supply of more oxygen to 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 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.
Hope this answers your question.
Regards,
