WebThe coronary arteries are major blood vessels in your body, supplying blood to your heart. They make it possible for your heart to beat and pump blood throughout your body. You have a right coronary artery (RCA) and a left main coronary artery (LMCA). Each contains smaller branches that go deep inside your heart muscle.
WebCardiac excitation-contraction coupling (Cardiac EC coupling) describes the series of events, from the production of an electrical impulse (action potential) to the contraction of muscles in the heart.
