Which statement is correct for exhaled air and inhaled air.a)Exhaled a...
Exhaled air contains more carbon dioxide and less oxygen.
Explanation:
When we breathe in, we inhale air from the environment, and when we breathe out, we exhale air from our lungs. The composition of inhaled and exhaled air is different due to the process of respiration.
Inhaled Air:
- Inhaled air is the air that we breathe in from the environment.
- It contains approximately 21% oxygen, 0.04% carbon dioxide, and 78% nitrogen.
- The oxygen in the inhaled air is important for the process of respiration, where it is utilized by our body cells to produce energy.
Exhaled Air:
- Exhaled air is the air that we breathe out from our lungs.
- It contains less oxygen and more carbon dioxide compared to inhaled air.
- Exhaled air typically contains around 16% oxygen, 4% carbon dioxide, and 78% nitrogen.
- The decrease in oxygen and increase in carbon dioxide is due to the gas exchange that occurs in our lungs during respiration.
- During respiration, oxygen is utilized by our body cells for energy production, and carbon dioxide, which is a waste product, is released.
- Therefore, exhaled air contains a higher concentration of carbon dioxide and a lower concentration of oxygen compared to inhaled air.
Summary:
In summary, exhaled air contains more carbon dioxide and less oxygen compared to inhaled air. This is because our body cells utilize oxygen for energy production, and carbon dioxide is released as a waste product.
