The left circumflex artery supplies which area of the heart?

Explanation:
The left circumflex artery runs in the left atrioventricular groove and sends obtuse marginal branches to the lateral wall of the left ventricle. That lateral-left-ventricle region is its primary territory, whereas the anterior wall is mainly supplied by the left anterior descending artery and the inferior wall by the right coronary artery (in most people; variations occur with coronary dominance). So, the lateral wall of the left ventricle is the area supplied by the left circumflex artery.
