Coronary arteries

The coronary arteries are the arterial blood vessels of coronary circulation. It moves oxygenated blood to the heart muscle. The heart needs constant supply of oxygen to work and survive, much like any other tissue or organ of the body.^[1] The coronary arteries wrap around the entire heart. The two main branches are the left coronary artery (LCA) and right coronary artery (RCA).

Figure A shows the location of the heart in the body. Figure B shows a normal coronary artery with normal blood flow. The inset image shows a cross-section of a normal coronary artery. Figure C shows a coronary artery narrowed by plaque. The buildup of plaque limits the flow of oxygen-rich blood through the artery. The inset image shows a cross-section of the plaque-narrowed artery.
