#mechanics of breathing MCQ

Cardiac Cycle and Regulation

Normal expiration during quiet breathing is mainly:

Correct option is B, Passive. In Cardiac Cycle and Regulation, the accurate description is Passive, and that is what you should commit to memory. Keep the definition tight and the role clear — the functional job described in the stem is exactly what Passive does in Cardiac Cycle and Regulation. Then Passive is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Passive. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Cardiac Cycle and Regulation

Intrapleural pressure normally remains:

The correct answer is C: Negative. In Cardiac Cycle and Regulation, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, Negative is the option that correctly names the structure, process, or principle asked for in Cardiac Cycle and Regulation. That is why Negative is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

At sea level, normal atmospheric pressure is approximately:

The correct answer is C: 760 mmHg. In Cardiac Cycle and Regulation, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, 760 mmHg is the option that correctly names the structure, process, or principle asked for in Cardiac Cycle and Regulation. That is why 760 mmHg is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists.
