Which of the following would be true during the inhalation phase of breathing?

A. lungs are inflated, oxygen concentration is high, and carbon dioxide concentration is low in the alveoli.
B. lungs are deflated, oxygen concentration is high, and carbon dioxide concentration is low in the alveoli.
C. lungs are inflated, oxygen concentration is low, and carbon dioxide concentration is high in the alveoli.
D. lungs are deflated, oxygen concentration is low, and carbon dioxide concentration is high in the alveoli.

I got 100%!!!:)

a

the answer is A.

Thanks iv been trying to find this stuff in the lesson itself and couldn't find anything this really helped. <3

I think the correct answer lies in how the question is interpreted. During the inhalation phase means what? At the beginning, in the middle, at the end, just where is during.

I guess they mean the middle, when the air has reached the lungs and the lungs are filled with air.

thanks

KENAI YOU KIND SOUL I WAS KINDA HAVING A MENTAL BREAKDOWN TJFDN

movie lover and kenziemack are both right :D

To determine which of the options is true during the inhalation phase of breathing, we need to understand the process of breathing and the changes that occur in the lungs during inhalation.

During inhalation, the diaphragm and intercostal muscles contract, causing the chest cavity to expand. This expansion increases the volume of the lungs, causing a decrease in pressure inside the lungs compared to the outside air. As a result, air is drawn into the lungs through the airways.

Based on this understanding, we can now evaluate the options:

A. Lungs are inflated, oxygen concentration is high, and carbon dioxide concentration is low in the alveoli.
During inhalation, the lungs are indeed inflated as the chest cavity expands. The increased volume of the lungs during inhalation creates space for air to enter. Additionally, during inhalation, oxygen-rich air is drawn into the lungs, which leads to a higher oxygen concentration in the alveoli, and the expulsion of carbon dioxide-rich air decreases the carbon dioxide concentration in the alveoli. Therefore, option A is likely to be true.

B. Lungs are deflated, oxygen concentration is high, and carbon dioxide concentration is low in the alveoli.
During inhalation, the lungs are not deflated; instead, they expand to draw air in. Therefore, option B is unlikely to be true.

C. Lungs are inflated, oxygen concentration is low, and carbon dioxide concentration is high in the alveoli.
During inhalation, oxygen-rich air is drawn into the lungs, leading to a higher oxygen concentration in the alveoli. Moreover, during inhalation, the expulsion of carbon dioxide-rich air decreases the carbon dioxide concentration in the alveoli. Therefore, option C is unlikely to be true.

D. Lungs are deflated, oxygen concentration is low, and carbon dioxide concentration is high in the alveoli.
During inhalation, the lungs do not deflate; instead, they expand to draw air in. Therefore, option D is unlikely to be true.

Based on the above analysis, the most accurate option for the statement would be:
A. Lungs are inflated, oxygen concentration is high, and carbon dioxide concentration is low in the alveoli.
