Why do both your heart rate and breathing rates increase when you exercise?

Increased metabolism required to make your body move more quickly or muscles work harder requires oxygen. The blood carries oxygen, and the lungs help the oxygen get into the blood. The heart goes faster so the oxygen can be delivered more quickly.
Over the long term, they actually decrease with exercise, as the body gets more tuned. The short term increase in pulse rate and breathing rate, are to get more oxygen to the muscles. The heart higher breath intake is to get more oxygen in the blood stream. The heart rate increase is to get the bloodflow higher so even more oxygen can get into the muscles.
