If you hold your breath, the carbon dioxide concentration in the blood will increase. Carbon dioxide is constantly produced by the body's metabolism, and constantly exhaled. So if it is not exhaled, it will start to build up.
Inhaled gases is oxegen and exhaled gases you CAN'T brethe in because it's carbon dioxide.
Exhaled breath has a higher concentration of carbon dioxide than inhaled air has. This is true whether you breathe through the nose or the mouth.
Inhaled air contains more oxygen than carbon dioxide and other gases. Exhaled air contains mostly carbon dioxide as the inhaled oxygen was used up to create energy. Waste carbon dioxide (and other unwanted gases) is then let out of the body and the cycle continues. :)Gas exchangeGas% in inhaled air% in exhaled airOxygen2116Carbon dioxide0.044Nitrogen7979
The carbon dioxide is exhaled.
When you inhale air the concentration is abut 21% of oxygen but in your lungs some of it gets consumed and replaced by carbon dioxide the concentration of exhaled oxygen depends on your metabolism and oxygen consumption.
The chemical formula of exhaled breath is Carbon Dioxide = CO2.
The chemical name of exhaled breath is carbon dioxide or CO2. The chemical name of inhaled breath is oxygen, or O2.
