Answer 2

Answer:-

In points ,

easy to understand

• The rate of breathing is also increased as a consequence. These responses collectively assist the animal to deal in case of emergencies.
• 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.
• It also raises the blood pressure, and allows more glucose to enter into the blood. All these responses together enable our body to deal with the emergency situations.
• When it reaches the heart, it beats faster to provide more oxygen to our muscles. The breathing rate further increases because of the contractions of the diaphragm and the rib muscles.
