Practice question

Pick B: Carotid and aortic bodies. Thinking about Lung Volumes, Capacities and Regulation in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: location matters here: Carotid and aortic bodies is the structure or site that matches the description. Hence Carotid and aortic bodies is correct. Treat this as a building block for the rest of Lung Volumes, Capacities and Regulation; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.
