Explanation:
1. Usually a change in breathing rate occurs when the body is undergoing an increase in body activity such as when one running or exercising. At such a point of running, for example, the body increases the levels of oxygen for the increased cellular respiration.
2. Using the same example of someone who is running, at such point, medical professionals believe that the heart which is part of the cardiovascular system begins to increase the frequency at which blood is circulated around the body. Thus, resulting in a change in heart rate (or change in the number of pumps per sec).
3. The following are a few ways:
- increase in sweat glands functions which brings out water from tiny holes in our skin to cool us off.
- increase in heart rate; pumping more blood into the body which helps in regulating body the temperature.
4. After you stopped exercising usually this occurs:
- the pumping rate of the heart reduces
- increase in muscle and body strength
This almost instant response tells us that our body has an automated ability to maintain internal body temperature (homeostasis).
