Want this question answered?
When we need more strength our breathing is faster so we can take some rest and breathe slowly.
Because you don't need to get as much oxygen to your blood for respiriation as you do not need more energy. When you are exercising you breathe faster to get that extra oxygen.
becouse body need to rest,and use energy just a litle (only for things like breathing)
When you are at rest, or sleeping, your heart beats slower. Because it is beating slower, blood travels more slowly through your body, and therefore more slowly through your lungs. As a result, you breath slower. When you do vigorous activity, your heart beats faster to supply blood to your body cells faster. This causes blood to race through your body and lungs, requiring you to breath a lot faster to keep up with the amount of blood that needs oxygen from your lungs.
no, they beat faster the more active they are
Headers help the engine breathe better thus better performance but the rest of the exhaust system needs to be included.
When you are at rest, the need for oxygen for your body decreased. This is due to reduced exercise and less movement that you make. When we move, we need energy and this energy is created by the process so called respiration. Respiration requires oxygen, lots of it. And when we are at rest, the level of respiration decreased as the need for energy is decreased and so the oxygen that we take in also decreased. When respiration is undergone, oxygen (in short O2) will be taken in, processed and carbon dioxide (CO2) will be given out. Respiration will increase the concentration of CO2 in our blood. As we rest, the CO2 conc. will decrease. There's a sensor in our artery (blood vessel) that monitors CO2 concentration. When the CO2 conc. is low, it will send information to our nervous system and tell them to breathe more slowly as we don't need so much O2. Vice versa on working. When we are working, our muscle and brain respirate faster as the need for energy increased. This, in turn will increase the conc. of CO2 and the sensor will send information to increase breathing rate. Resources: my memory of 11th grade study in school a year ago
At rest you are using less oxygen - and making less CO2.

It will come slowly as you build muscle on the rest of your body. It will come slowly as you build muscle on the rest of your body.
(My guess is that) When you're running your muscles have to work harder, so the muscles in your heart start to work faster & pumping more blood. But you're breathing isn't exactly a muscle so you start to breathe harder trying to catch up with the rest of your body.
