The left circumflex branch supplies which area of the heart?

Explanation:
The left circumflex artery primarily supplies the lateral wall of the left ventricle. It courses in the left atrioventricular groove and gives obtuse marginal branches that perfuse the lateral LV surface. The anterior septum is mainly supplied by the left anterior descending artery, the inferior wall by the right coronary artery in most people (or the posterior descending artery in left-dominant hearts), and the right ventricle is typically supplied by branches of the right coronary artery.
