  1. Which layer of the heart wall contains the Purkinje fibers?

    Answer: Endocardium

    Purkinje fibers are specialized conduction cells located in the subendocardial layer of the endocardium.

  2. The coronary sinus drains deoxygenated blood from the myocardium into which cardiac chamber?

    Answer: Right atrium

    The coronary sinus empties venous blood from the coronary circulation directly into the right atrium.

  3. What is the normal range for left ventricular end-diastolic pressure (LVEDP)?

    Answer: 6–12 mmHg

    Normal LVEDP is approximately 6–12 mmHg, reflecting left ventricular filling pressure.

  4. Which valve separates the left atrium from the left ventricle?

    Answer: Mitral valve

    The mitral (bicuspid) valve is the atrioventricular valve on the left side of the heart.

  5. The 'a' wave on a jugular venous pulse (JVP) tracing corresponds to which event?

    Answer: Atrial contraction

    The 'a' wave reflects the rise in atrial pressure caused by atrial contraction at end-diastole.

  6. Which structure carries oxygenated blood from the lungs to the left atrium?

    Answer: Pulmonary veins

    Pulmonary veins are the only veins in the body that carry oxygenated blood, returning it from the lungs to the left atrium.

  7. Starling's law of the heart states that stroke volume increases in response to increased:

    Answer: Preload (end-diastolic volume)

    Frank-Starling's law describes the intrinsic ability of the heart to increase stroke volume in response to greater ventricular filling (preload).
