I'm not sure, but I'm guessing C. Vital capacity seems like it would be important for exercise.

I think the answer is A. Tidal volume increases during exercise to meet the body's increased oxygen demand.

I’m confused because I thought vital capacity was more relevant to overall lung function, not just during exercise. Is it C)?

I feel like we did a practice question similar to this, and it focused on tidal volume as well. I’m leaning towards A).

The key here is "primarily." I think A) Tidal volume is the best answer, since our breaths get deeper even if the rate also increases during exercise.

I'm leaning towards D) Total lung volume. Exercising expands our lung capacity to handle the extra air flow, right? But I'm not 100% sure.

B) Breathing frequency seems like a good possibility. Our breathing rate tends to go up during exercise to meet the body's increased oxygen demands.

Hmm, I'm not sure about this one. I know ventilation increases, but I'm not confident which specific factor is the primary driver. I'll have to think it through carefully.

I think the answer is A) Tidal volume. During exercise, our breathing becomes deeper to bring in more oxygen.
