Question

At the peak of the inspiratory phase, the alveoli in the lungs contain A. high quantities of carbon dioxide B. minimal levels of oxygen and carbon dioxide C. equal levels of oxygen and carbon dioxide D. more oxygen than carbon dioxide

Answer 1

At the peak of the inspiratory phase, the alveoli in the lungs contain more oxygen than carbon dioxide.

Step-by-step explanation:

At the peak of the inspiratory phase, the alveoli in the lungs contain more oxygen than carbon dioxide. During inhalation, oxygen is taken in and diffused into the bloodstream while carbon dioxide is exhaled. This leads to higher levels of oxygen in the alveoli compared to carbon dioxide. As the oxygen-rich blood flows to the rest of the body, it delivers oxygen to the cells and removes carbon dioxide, maintaining the balance.
