Practice question

Go with A — Systolic and diastolic pressures. Within Cardiac Cycle and Regulation, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, this is mainly a definition check, and Systolic and diastolic pressures is the standard term or meaning used in Cardiac Cycle and Regulation. Holding that picture in mind makes Systolic and diastolic pressures 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 Systolic and diastolic pressures.
