Left coronary artery: This is the artery that originates from the left side of the aorta. Most commonly, it bifurcates into two different arteries: the circumflex artery and the left anterior descending artery. It supplies oxygenated blood to the left part of the heart. (1,3)

ANTERIOR INTERVENTRICULAR ARTERY

Anterior interventricular artery: This artery originates from the left main coronary artery, descends along the interventricular sulcus, and gives rise to other important branches. (1,2,3)

Conal branch of anterior interventricular artery: A small branch that supplies the conus arteriosus, part of the right ventricle of the heart. (1,3)

Anterior ventricular branches of anterior interventricular artery: These branches supply the anterior wall of the heart. (2,3)

Diagonal branch of anterior interventricular artery: Commonly branches off diagonally to supply blood to the left side of the heart. (1,3)

Septal branches of anterior interventricular artery: Branch off to supply a significant portion of the interventricular septum. (1,3)

CIRCUMFLEX ARTERY OF HEART

Circumflex artery of heart: Curves around the heart, supplying blood to the left atrium and the side and back of the left ventricle. (1,2,3)

Atrial branches of circumflex artery of heart: Supply blood to the left atrium of the heart. (2,3)

Atrial anastomotic branch of circumflex artery of heart: A connecting branch between the circumflex artery and other arteries supplying the left atrium.

Left marginal branch of circumflex artery of heart: Supplies blood to the lateral wall of the left ventricle. (1,2,3)

Inferior left ventricular branch of circumflex artery of heart: Descends to the inferior wall of the left ventricle, supplying it with blood. (2,3)
