Everyday functions of the body need oxygen. When these processes happen, carbon dioxide is produced as a waste . In This job our lungs provide the processes with intake of oxygen and to get rid of the waste gas, carbon dioxide.
our brain constantly gets signals from our body which detect the amount of oxygen and carbon dioxide in our blood.
where brain sends signal to the muscles involved in breathing and adjust our breathing rate depending on how active we are.
When we are active, our breathing can increase up to about 40-60 times a minute to cope with the extra demand. The delivery of oxygen to our muscles also speeds up, so they can do their job efficiently. The increase in our breathing also makes sure there is no build-up of carbon dioxide in your bloodstream.
