why does exhaled air contain more oxygen than inhaled air
Answers
The result is that the exhaled air contains less oxygen and more carbon dioxide than the inhaled air. The air in the lungs also becomes humidified with water before it is exhaled. ... The rates at which oxygen, carbon dioxide, and water are exchanged with the body are very important.
ANSWER:
The percentage of exhaled oxygen is more than inhaled air because in exhaled air all types of gases present in atmospheric air except that the percentage of carbon dioxide is very high and the percentage of oxygen is very low.
EXPLANATION:
The main gas present in inhaled and exhaled is nitrogen. The other gases are oxygen, carbon dioxide and then the percentage of other gases present in air.
The percentage of nitrogen in inhaled air is 78%, the percentage of oxygen is 21%, 0.04% is carbon dioxide and rest 0.096 is water vapour and in other side exhaled air contain 78% nitrogen, 17% oxygen , 4% carbon dioxide and rest 3% is water vapour.
