Alveolar Air vs. Expired Air CO2 Concentration
Alveolar air refers to the air found in the alveoli of the lungs, where gas exchange takes place. On the other hand, expired air is the air that is exhaled out of the body. The concentration of CO2 in these two types of air differs due to the process of gas exchange in the lungs.
Explanation:
- Alveolar air: In the alveoli, oxygen from the inhaled air diffuses into the bloodstream, while CO2 from the bloodstream diffuses into the alveoli to be exhaled out. This exchange results in a higher concentration of CO2 in the alveolar air compared to the inspired air.
- Expired air: When we exhale, the air that is pushed out of the lungs contains a higher concentration of CO2 compared to the alveolar air. This is because the CO2 that was exchanged into the alveoli during inhalation is now being expelled out of the body.
Therefore, the correct statement is that there is more CO2 in alveolar air than in expired air. This is due to the process of gas exchange that occurs in the lungs, leading to a higher concentration of CO2 in the alveoli before it is exhaled out of the body.
