Question

How does mouth to mouth work if we breathe out co2?

Answer 1

Answer:

when o2 enter the nassel chamber and flow oesopahagu pipe and reach alveolar site and flow the blood then. alveolar site reach the co2 through the epiglotus and enter the oesophagus pipe and exhale the mouth and nassal camber

pathway of air = nassal chamber - oesophagus - glottus - pharynx - bronchioles and last is alveolar

Answer 2

Answer:

That's a good question. In order to perform a successful mouth-to-mouth breathing, you have to inhale and exhale very quickly to prevent your lungs to process the oxygen that you inhale. By doing so you're reducing the emission of CO2 in your exhales and increasing the levels of oxygen
