All cells in our body need oxygen to create energy efficiently. When the cells create energy, however, they make carbon dioxide. We get oxygen by breathing in fresh air.
Everyday functions of the body like digesting your food, moving your muscles or even just thinking, need oxygen. When these processes happen, a gas called carbon dioxide is produced as a waste product. The job of your lungs is to provide your body with oxygen and to get rid of the waste gas, carbon dioxide.
Your brain constantly gets signals from your body which detect the amount of oxygen and carbon dioxide in your blood.
Your brain will send signals to the muscles involved in breathing and adjust your breathing rate depending on how active you are.
When you’re active, your breathing can increase up to about 40-60 times a minute to cope with the extra demand. The delivery of oxygen to your muscles also speeds up, so they can do their job efficiently. The increase in your breathing also makes sure there’s no build-up of carbon dioxide in your bloodstream.
how do we breath?
The diaphragm (a muscle under the lungs) moves down. This makes more space for the lungs which fill up with air from the mouth and nose. The air moves through tubes in the lungs to tiny air sacs called alveoli. Oxygen passes from these into the blood, which carries the oxygen to all the cells in the body.
