Q1 · Cardiac Cycle
NEET PGMediumExplanation
The 'a' wave reflects right atrial contraction. It is absent in atrial fibrillation and becomes a large cannon wave in complete heart block, when the atrium contracts against a closed tricuspid valve.
Q2 · Cardiac Output
NEET PGEasyExplanation
Cardiac output is stroke volume multiplied by heart rate, about 5 litres per minute at rest. Stroke volume depends on preload, afterload and contractility.
Q3 · Frank-Starling Law
NEET PGMediumExplanation
The Frank-Starling mechanism means greater end-diastolic volume, or preload, stretches cardiac muscle, increasing contractile force and stroke volume. This matches output to venous return.
Q4 · ECG Waveforms
NEET PGMediumExplanation
The QRS complex represents ventricular depolarisation. The P wave is atrial depolarisation, the T wave is ventricular repolarisation, and the PR interval reflects AV nodal conduction delay.
Q5 · Baroreceptor Reflex
HardExplanation
Baroreceptors in the carotid sinus and aortic arch sense increased pressure and increase parasympathetic while decreasing sympathetic outflow, lowering heart rate and causing vasodilation to restore normal pressure.
Q6 · Cardiac Pacemaker
EasyExplanation
The SA node has the fastest intrinsic firing rate, about 60 to 100 per minute, and sets the heart rhythm. If it fails, lower pacemakers in the AV node and His-Purkinje system take over at slower rates.
Q7 · Heart Sounds
MediumExplanation
S1 is produced by closure of the atrioventricular, mitral and tricuspid, valves at the start of systole. S2 results from closure of the aortic and pulmonary semilunar valves.
Cardiovascular sits within Physiology, which carries the same syllabus in both exams. This set runs to 7 questions, each tagged Easy, Medium or Hard, 1 of them at Hard, and 4 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Cardiovascular marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Physiology examiners keep returning to.
FAQ
Yes. Every question and explanation in this Cardiovascular set is free and open — no login, no form and no payment. The explanation appears the moment you answer.
Cardiovascular sits within Physiology, which appears in the same form in both syllabuses. System-wise physiology with the mechanisms examiners test most: cardiac and respiratory regulation, renal handling, endocrine axes and nerve conduction.
