How does our body respond when adrenaline is secreted into the blood ?

Explanation

adrenaline is secreted into the blood, it is carried to different parts of the body. One of the target organs of the hormone is the heart. The following reactions are observed in the body as a response to the hormone:
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.
