EXPLANATION:
When we exercise the breathing rate is automatically enhanced because when we exercise we tend to work harder and our muscles work faster thus they need extra supply of oxygen to balance this hard work.
The oxygen is carried to the parts of the body by means of blood , when there is a high oxygen requirement the requirement of blood flow is also higher thus the heart rate also is higher.
