Question 1 Report

Exhaled air differs from inhaled air in that it
Answer Details
Exhaled air differs from inhaled air in that it usually has more carbon dioxide and more water vapor. When we breathe in, we inhale oxygen and exhale carbon dioxide. The exhaled air also contains moisture from the lungs, which can make it slightly warmer and more humid than the inhaled air. Therefore, the correct option is "usually has more water vapor" and "less amount of oxygen".
