Coronary circulation of the heart

This brief video tutorial discusses why the heart needs its own circulatory system, identifies the principle coronary arteries and cardiac veins and briefly discusses coronary dominance. 0:00. Introduction 0:19. What is the coronary circulation? 2:14. Function of coronary arteries 2:27. Coronary arteries are "end arteries" (at 3:19 i am sorry for my mistake ... cardiac arrest is NOT the same as a heart attack) 3:43. Right coronary artery (RCA) - 5:04. Sinuatrial nodal (SA) artery - 5:18. Right marginal artery (acute marginal artery) - 6:01. Posterior descending artery (PDA) - 6:50. Definition of coronary dominance (right dominant, left dominant, co-dominant) - AV nodal artery 8:50. Left coronary artery (LCA) 9:33. Left anterior descending artery (LAD); Anterior interventricular artery 10:39. Left circumflex artery (LCX) 11:27. Left marginal artery (obtuse marginal artery) 12:01. Cardiac veins (coronary sinus, great cardiac vein, middle cardiac vein, small cardiac vein) 13:34. Regulation of blood flow in coronary circulation 14:15. In-a-nutshell 15:05. References
