Practice question

Go with C — Remaining after maximum expiration. Within Lung Volumes, Capacities and Regulation, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, Remaining after maximum expiration is the option that correctly names the structure, process, or principle asked for in Lung Volumes, Capacities and Regulation. Holding that picture in mind makes Remaining after maximum expiration feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Remaining after maximum expiration.
