Two Main Coronaries

Satisfactory Essays
1. The two main coronary arteries that supply blood to the hart are the left main coronary artery and the right coronary artery.

The left main coronary artery provides blood to the left part of the heart (e.g. left atrium and left ventricle). In particular, the left main coronary branches off into the circumflex artery and the left anterior descending artery. If there is occlusion in the circumflex coronary, then there is infarction in the left atrium and the side and back of the left ventricle. In addition, if there is blockage in the left anterior descending artery, then there is infarction in the front and bottom of the left ventricle, and the bottom of the sepum.

The right coronary artery supplies blood into the right area of the heart
