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.

Why does exercise have an effect on pulse rate and breathing?
Because the demand for oxygen and glucose increases, and the heart and lungs need to speed up to keep up with the demand.

What causes heart rates to increase and decrease?
fudge

Check out the site http://www.heartmonitors.com/exercisetips/heart_rate_basics.htm for a chart on heart rates given age and activity level. Be sure to note that your heart rate will increase with the level of excercise.
Why do breathing rates increase in crowded rooms?
Your rate of breathing increases in a crowded area because there is less oxygen. This is because there are more people breathing in the oxygen.
Why do breathing and pulse rates not return immediately after exercise stops?
The body needs to neutralise the lactic acid
When is the best time to check resting heart rates?
Before any exercise
