The left main coronary artery subdivides into the: - Answer-Left anterior descending and circumflex arteries. AV valves prevent backflow during: - Answer-Ventricular contractions. The S1 heart sound is the sound of the: - Answer-Mitral valve and Tricuspid valves closing. The S3 gallop sound is indicative of: - Answer-Heart failure.
