Where do coronary veins drain to?
The great cardiac vein, the middle cardiac vein, and the small cardiac vein all drain into the coronary sinus (which opens into the right atrium). The anterior cardiac veins drain directly into the right atrium.
What does coronary veins mean?
Medical Definition of coronary vein 1a : any of several veins that drain the tissues of the heart and empty into the coronary sinus. b : cardiac vein —not used technically. 2 : a vein draining the lesser curvature of the stomach and emptying into the portal vein.
What is the function of coronary vein?
The primary physiological function of the coronary veins is to carry deoxygenated blood from the myocardium and empty them into the chambers of the heart.
What is the difference between coronary arteries and cardiac veins?
Coronary arteries supply oxygenated blood to the heart muscle. Cardiac veins then drain away the blood after it has been deoxygenated.
What are the major coronary veins?
The major venous vessels of the human heart are: coronary sinus, the anterior interventricular veins, left marginal veins, posterior veins of the left ventricle, and the posterior interventricular veins (see also the Coronary System Tutorial).
What is the largest vein that drains the heart?
coronary sinus
The coronary sinus is the largest cardiac vein in terms of diameter. Various landmarks have been described as the location of the coronary sinus origin, including where the oblique vein of the left atrium meets the great cardiac vein and at the valve of Vieussens [4,7].
What are the 3 main coronary arteries?
The coronary arteries are also called the epicardial arteries because they run along the outer surface of the heart on the epicardium; the main ones are the left coronary artery and the right coronary artery. The left coronary artery divides into the left anterior descending and the left circumflex arteries.
What are the three main cardiac veins?
Which coronary artery is most commonly blocked?
The LAD artery is the most commonly occluded of the coronary arteries. It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system.
What are the three major veins of the heart?
The major blood vessels that are connected to the heart include the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs, where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart) and the …
What vein goes to the heart?
Blood Flow Through the Heart Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.
