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.
The largest vein, termed the great cardiac vein, accompanies the anterior interventricular artery, turning beneath the left atrial appendage to join the coronary sinus.
Great cardiac vein
|Drains from||Small venules of the apex of heart|
|Tributaries||Venules of the ventricles and left atrium, left marginal vein, oblique vein of left atrium (of Marshall)|
|Drains to||Coronary sinus|
|Drainage area||External layer of the myocardium of the ventricles and left atrium|
The small cardiac vein is an inconstant vessel that receives blood from the back of the RA and RV, runs in the coronary sulcus between the RA and RV parallel to the right coronary artery, and empties into either the CS, the middle cardiac vein, or the RA.
The small cardiac vein, also known as the right coronary vein, is a coronary vein that drains the right atrium and right ventricle of the heart. Despite its size, it is one of the major drainage vessels for the heart.
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.
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.
Overview of the main coronary arteries and cardiac veins (20 structures).
Structure Left anterior descending artery. Left circumflex artery. Posterior descending artery. Ramus or intermediate artery.
The right ventricle receives deoxygenated blood from the right atrium, then pumps the blood along to the lungs to get oxygen. The left ventricle receives oxygenated blood from the left atrium, then sends it on to the aorta.
The great cardiac vein, small and middle cardiac veins drain into the coronary sinus. The coronary sinus empties into the right atrium. Thebesian veins drain where? Arise in the myocardium and drain into all chambers of the heart.
The carotid arteries are major blood vessels in the neck that supply blood to the brain, neck, and face. There are two carotid arteries, one on the right and one on the left. In the neck, each carotid artery branches into two divisions: The internal carotid artery supplies blood to the brain.
Arterial thrombosis is a blood clot that develops in an artery. It’s dangerous as it can obstruct or stop the flow of blood to major organs, such as the heart or brain. If a blood clot narrows one or more of the arteries leading to the heart, muscle pain known as angina can occur.
The cardiac veins returns deoxygenated blood (containing metabolic waste products) from the myocardium to the right atrium. This blood then flows back to the lungs for reoxygenation and removal of carbon dioxide.
two or more arteries converge to supply the same body region is called. anastomosis.
