Our bodies burn fuel much like a car does. When you press on the gas, more fuel and air is sucked into the engine and combusted to produce more horsepower. When we exercise it is like we are pushing down on our own accelerator pedal that pumps more sugar and oxygen into our muscles to produce more power. Our heart rate and breathing increases to allow us to burn more of our fuel which, instead of gas, is adenosine triphosphate (ATP).
The science is that when we exercise our muscles need more energy and oxygen to move and so we need to breathe more air. Then the air goes down the trachea, through the bronchi and bronchioles and finally into air sacs called alveoli where the oxygen is diffused through the thin walls of blood vessels called capillaries. At the same time carbon dioxide is diffused through the wall from the blood vessel to the air sac and back out the same way the oxygen came in. Then the oxygen is transported around the body through the blood vessels and into the muscles.Then the deoxygenated blood goes to the heart and lungs to become oxygenated. This supplies oxygen to all the body tissues. As more energy is needed in the muscles more oxygen is needed in the blood so respiration increases.
When you exercise, your muscles need more oxygen and fuel to continue working. Your heart rate then increases to get more fuel and oxygen to them more quickly. Depending on how hard you are exercising, your heart will speed up accordingly to give your muscles the power to keep going.

Why does the heart rate go up when being on high mountains?
Parts of your body, especially your muscles, require much more oxygen during exercise, which reaches them via your blood traveling through blood vessels. This means two things: your heart must beat faster to provide the oxygen more rapidly; and you must breathe faster and harder so that your lungs can oxygenate the blood.

What activities make your heart rate increase?
As your muscles work harder, they need more nutrients. The brain tells the heart to beat faster to provide more nutrients to the muscles. You also breath heavier and more rapidly because your body needs more oxygen the harder you work.
Increased heart rate and shortness of breath?
Increased heart rate and shortness of breath is a symptom most commonly experienced by overweight people. If you are not overweight the cause of this could be smoking, eating of fatty and sugary foods, lack of exercise and not enough interaction with the opposite sex. To eliminate these symptoms you must eat healthily, not smoke, exercise frequently and if problems still persist seek medical advice immediately as this is a potentially serious situation.
Does anyone have any harder boyz than kut7?
Yes. Many people have harder boyz than kut7. For example, your mother has harder boyz. Your father has loved harder boyz.
What causes people's heart rate to speed up?
I did an experiment and it came out younger people have faster heart rates then older people. This may be because the younger peoples hearts are not fully developed and are more expandable which makes the heart pump faster. Or, it may be because younger people have a faster metabolism.
What drives people to work harder and faster?
Money!
Do slimmer people have better breathing?
I would say yes because I used to be way overweight and it it was harder to breath then. When I started losing weight, it became easier to breath.
Is there a music video with blue cartoon people in it?
Daft punk-harder better faster stronger
Why do some people breath heavily when falling asleep?
Some people breath heavily when falling asleep to release all the carbon dioxide in their lungs faster, to provide more oxygen to the brain.
How does heart rate differ from a female who is fit and a female who is not fit?
People who are fit typically have a slower heartbeat because the heart does not have to work as hard to pump blood, and un-fit people have a faster heartbeat because their heart has to work harder to support them since they don't exercise enough.
Why does high humidity increase the difficulty of breathing for people with chronic respiratory disease?
there is lots of water in the air so its harder for you to breath.
Why do brakes go bad faster during the summer?
most people drive faster in the dry than in the wet, therefore have to use brakes harder to stop
Do people type faster in cold or hot temperatures?
Based on logic and experience, I would say people type faster in warmer temperatures, up to the point where the heat starts causing physiological problems. The colder it is, the colder your fingers get. The colder your fingers get, the harder it is to control them, and the harder it is to type. So I would say people type faster in hot temperatures, up to a certain point.
Why do people suffering from anxiety attacks breath into brown paper bags and not plastic bags?
ANSWER. because they're not stupid enough to use something that can suffocate them, its harder to breath a paper bag into your lungs/throat.
