Practice question
Question
Vital capacity (VC) is the sum of:
Explanation
Pick C: IRV + TV + ERV. 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: IRV + TV + ERV is the option that correctly names the structure, process, or principle asked for in Lung Volumes, Capacities and Regulation. Hence IRV + TV + ERV 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.
