Where does the great cardiac vein collect blood?

The coronary sinus serves as the primary collector of cardiac venous blood and is located in the atrioventricular groove on the diaphragmatic surface of the heart [6-7]. The coronary sinus is the largest cardiac vein in terms of diameter.

Where does blood flow from the great cardiac vein?

Function: This cardiac vein returns deoxygenated blood (metabolic waste products) from the anterior surfaces of the left ventricle. Other Nomenclature: The section of the great cardiac vein that courses anteriorly in between the left and right ventricle is also known as the anterior interventricular vein.

What artery does the great cardiac vein travel with?

The anterior interventricular artery is viewed as a caudal, anterior continuation of the left coronary artery. It travels inferolaterally within the anterior interventricular groove towards the cardiac apex. It is more often than not, covered by bridging myocardial fibers, as well as sections of the great cardiac vein.

What is the destination of coronary venous blood?

Most cardiac veins collect and return blood to the right atrium through the coronary sinus; there may or not be a Thebesian valve covering the ostium of the coronary sinus.

Does the great cardiac vein carry oxygenated blood?

Coronary circulation is the circulation of blood in the blood vessels that supply the heart muscle (myocardium). Coronary arteries supply oxygenated blood to the heart muscle, and cardiac veins drain away the blood once it has been deoxygenated.

What is another name for the great cardiac vein?

The great cardiac vein, also called the anterior interventricular vein, is a large blood vessel found on the anterior (sternocostal) surface of the heart.

What is the largest cardiac vein?

The coronary sinus serves as the primary collector of cardiac venous blood and is located in the atrioventricular groove on the diaphragmatic surface of the heart [6-7]. The coronary sinus is the largest cardiac vein in terms of diameter.

Which artery carries the supply of blood towards heart?

Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away.

Which coronary artery supplies the most blood to the heart?

The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle. The right coronary artery supplies blood mainly to the right side of the heart.

Do most cardiac veins drain directly into the right atrium?

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 Veins collect blood from the heart muscle?

Coronary veins (in blue) – take oxygen-poor (“deoxygenated”) blood that has already been “used” by muscles of the heart and returns it to the right atrium.

Where do most cardiac veins drain?

Coronary veins

  • cardiac veins which drain into the coronary sinus: great cardiac vein. …
  • the anterior cardiac veins which drain directly into the right atrium.
  • the venae cordis minimae (smallest cardiac veins a.k.a. Thebesian veins) which drain directly into all four chambers, but are most frequent in the right atrium.

How many veins are in the heart?

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

What is the only vein in the body that carries oxygenated blood?

However, the pulmonary vein is the only vein in the body that carries oxygen-rich blood (from the lungs back to the heart to be pumped into the rest of the body) and the pulmonary artery is the only artery in the body that carries oxygen-poor blood (to the lungs to be oxygenated before being sent to the heart to be …

What is the function of small cardiac vein?

Function. The small cardiac vein receives blood from the posterior portion of the right atrium and ventricle.

Do arteries carry blood away from the heart?

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
