Final answer:
The lungs inhale oxygen and exhale carbon dioxide.
Step-by-step explanation:
The lungs do not inhale water vapor and carbon dioxide. In fact, the lungs play a crucial role in breathing, which involves inhaling oxygen and exhaling carbon dioxide.
When we inhale, we take in air, which contains oxygen. This oxygen is transported to the lungs, where it enters the bloodstream and is carried to the body's cells for energy production. Additionally, when we exhale, carbon dioxide, which is a waste product of cellular respiration, is expelled from the body.
In summary, the lungs inhale oxygen and exhale carbon dioxide, not water vapor and carbon dioxide.
