Card 1 of 5
Question
Select all correct statements about cardiac output in this basic model.
- It is heart rate multiplied by stroke volume
- It represents volume pumped per unit time
- It is the sum of heart rate and stroke volume
- It is identical to the residual end-systolic volume
Card 2 of 5
Question
Which quantity is the volume ejected by a ventricle in one beat?
- End-systolic volume
- Cardiac output
- End-diastolic volume
- Stroke volume
Card 3 of 5
Question
Which change most directly represents an increase in preload?
- Greater arterial opposition to ejection alone
- Longer conduction through the AV node alone
- Greater end-diastolic myocardial stretch
- A valve's number of cusps
Card 4 of 5
Question
In a physiology teaching model, arterial opposition to ventricular ejection increases while initial filling is held constant.
Card 5 of 5
Question
Explain why increased ventricular filling within physiological limits can increase stroke volume without requiring a different pacemaker rate.

What is inside

50 quizzes: 3 fill-blank, 23 mcq, 6 true-false-explanation, 4 matching, 8 clinical-vignette, 3 mrq, 2 open-question, 1 sequencing. Introductory Cardiovascular Foundations contains 50 flashcards and 50 quizzes across heart chambers and valves; the cardiac cycle and heart sounds; conduction and refractory behaviour; ECG P, QRS and T events; cardiac output, preload, afterload, pressure gradients and resistance; vessel structure and venous return; basic mechanisms of lisinopril, metoprolol, furosemide and nitroglycerin; and definitions of atherosclerosis, myocardial ischaemia, infarction and heart failure.25 covered objectives, atomic concept links and real source evidence support targeted feedback and recommendations. Drug mechanisms are country-neutral pharmacology knowledge, not therapeutic choices, dosing or individual prescribing guidance. This set does not establish supervised clinical competence.
