Most physiological measures are taken during eupnea, or quiet breathing. This means that:

Muscular force is used for inspiration but not expiration.

Most physiological measures are taken during eupnea, or quiet breathing. This means that:

Our practice problem tells us that most physiological measures are taken during eupnea or quiet breathing, and then it says this means that, and it gives us four options here. Well, quiet breathing, that eupnea, remember, that's that sort of restful breathing when you're not thinking about breathing. And importantly, what's going on there is that you are using the muscles of the diaphragm and the intercostal muscles for inspiration, but expiration is just the relaxation of those muscles. As I look down, that's option b. So that's getting my big old green checkaroo. I think that's my answer. Our other options here, we have a, ventilation is a passive process that does not use muscular force. It is not passive ventilation. You need to use muscles to get air in and out of the lungs. You need to move that air. C says muscular force is used for expiration but not inspiration. That's backwards. You use it for inspiration not expiration. So crossing that one out. D says muscular force is used for both inspiration and expiration. That's also wrong for the obvious reasons we've already stated. So my answer is b. Muscular force is used for inspiration, but not expiration during quiet breathing or buprenorphine. That's my answer.

Most physiological measures are taken during eupnea, or quiet breathing. This means that:

Muscular force is used for inspiration but not expiration.

Ventilation is a passive process that does not use muscular force.

Muscular force is used for expiration but not inspiration.

Muscular force is used for both inspiration and expiration.
