Which valve separates the left atrium from the left ventricle?
Answer: Mitral valve
The mitral valve (bicuspid valve) is located between the left atrium and left ventricle.
The Frank-Starling mechanism states that increased ventricular filling leads to:
Answer: Increased stroke volume
The Frank-Starling law states that greater myocardial stretch from increased preload results in a stronger contraction and higher stroke volume.
Which coronary artery primarily supplies the anterior wall of the left ventricle?
Answer: Left anterior descending artery
The left anterior descending (LAD) artery supplies the anterior wall and apex of the left ventricle.
Normal left ventricular ejection fraction (LVEF) range is approximately:
Answer: 55–70%
A normal LVEF is 55–70%, indicating the percentage of blood ejected per contraction.
The chordae tendineae attach the atrioventricular valve leaflets to the:
Answer: Papillary muscles
Chordae tendineae are fibrous cords that connect AV valve leaflets to papillary muscles, preventing valve prolapse during systole.
During systole, what happens to the mitral valve?
Answer: It closes to prevent regurgitation into the left atrium
During systole, the mitral valve closes as left ventricular pressure exceeds left atrial pressure, preventing backflow.
