Admin 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).
Where are coronary veins?
Near the left atrium, the great cardiac vein veers to the left and enters the coronary sulcus (= between the left atrium and ventricle), where it extends to the back side of the heart. One or more left marginal veins typically merge with the great cardiac vein as it traverses the lateral ventricular wall.
What is the largest heart artery?
aorta
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
Is coronary sinus a vein?
At a length varying from 3 to 5 cm and a caliber of 1 cm, the coronary sinus is the largest coronary vein. It arises along the posterior aspect of the heart between the left atrium and the left ventricle.
What are the 3 main veins of the heart?
Major Blood Vessels of the Heart
- The pulmonary trunk artery. The left pulmonary veins and. right pulmonary veins return oxygenated blood from the lungs to the left atrium.

How many coronary veins are there?
Coronary veins are responsible for draining deoxygenated blood from the myocardium into the cardiac chambers. Comprised of two venous systems, coronary veins classify into either the greater cardiac venous system or the smaller cardiac venous system.
Which one is the largest vein of the heart situated in the posterior part of coronary sulcus?
Coronary Sinus: The Great Coronary Vein empties into the Coronary Sinus, which in turn Empties into the Pulmonary Artery into the Right Atrium. The Coronary Sinus is located deep to the great vein, on the posterior wall of the Right Atrium.
