The great cardiac vein (GCV) runs in the anterior interventricular groove and drains the anterior aspect of the heart where it is the venous complement of the left anterior descending artery. It is the main tributary of the coronary sinus.
Where is the great vein?
Anatomical terminology
The great cardiac vein (left coronary vein) begins at the apex of the heart and ascends along the anterior longitudinal sulcus to the base of the ventricles. It then curves around the left margin of the heart to reach the posterior surface.
Why is the great cardiac vein important?
The greater cardiac venous system drains the majority of the deoxygenated blood, while the smaller cardiac venous system drains a smaller portion of the deoxygenated blood to its respective heart chambers.
Where does the blood go from the great cardiac vein?
It empties into the coronary sinus at the crux of the heart. The lateral, posterolateral, and posterior cardiac veins of the left ventricle receive blood from their respective aspects of the left ventricle before emptying into the coronary sinus along the left AV groove.
What are the areas drained by the great cardiac vein?
The vein drains the: anterior surface of the right and left ventricles (up to and including the apex) anterior interventricular septum. portions of the left atrium.

What is great vein in heart?
The great cardiac vein (GCV) runs in the anterior interventricular groove and drains the anterior aspect of the heart where it is the venous complement of the left anterior descending artery. It is the main tributary of the coronary sinus.
What is the cardiac vein?
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. Importance in cardiovascular diseases: … Typically cardiac veins are free of atherosclerotic plaques.
Where is the OM artery?
The obtuse marginal (OM) arteries sometimes referred to as lateral branches are branch coronary arteries that come off the circumflex artery. There can be one or more obtuse marginal arteries. It typically traverses along the left margin of heart towards the apex.
What is the function of coronary arteries and veins?
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. The coronary arteries wrap around the outside of the heart.
What is the function of the small cardiac vein?
The small cardiac vein contributes to the venous drainage of the external layer of the myocardium of the posterior right atrium and right ventricle.
Is the great cardiac vein oxygenated or deoxygenated?
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.
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 is a convergence of two arteries called?
two or more arteries converge to supply the same body region is called. anastomosis.
Which veins drain into coronary sinus?
The coronary sinus receives drainage from most epicardial ventricular veins, including the oblique vein of the left atrium (and other left and right atrial veins), the great cardiac vein, the posterior vein of the left ventricle, the left marginal vein, and the posterior interventricular vein.
What vein drains into the right atrium?
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. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.
What drains blood into the right atrium?
The two major systemic veins, the superior and inferior venae cavae, and the large coronary vein called the coronary sinus that drains the heart myocardium empty into the right atrium.
Where is the apex in the heart?
The heart sits atop the diaphragm and its apex is close to the anterior surface of the thoracic cavity. With every beat, the heart twists forward and the apex taps against the chest wall, producing the apex beat. This can be felt in the fifth left intercostal space.
What are the 3 major veins?
The aorta is the large artery leaving the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
What are the 3 types of veins?
What are the different types of veins?
- Deep veins are located within muscle tissue. …
- Superficial veins are closer to the skin’s surface. …
- Pulmonary veins transport blood that’s been filled with oxygen by the lungs to the heart.
What is a great vessel?
The great vessels is the collective term given to the major arteries and veins that convey blood to and away from the heart: aorta. pulmonary artery. pulmonary veins. superior vena cava.
What are the 3 coronary arteries?
Right Coronary Artery (RCA)
- Right marginal artery.
- Posterior descending artery.
Which artery is the most common to have blockage?
Although blockages can occur in other arteries leading to the heart, the LAD artery is where most blockages occur. The extent of the blockage can vary widely from 1% to 100%.
How long does a stent last in heart?
How long will a stent last? It is permanent. There is just a 2–3 per cent risk of narrowing coming back, and if that happens it is usually within 6–9 months.
What is the largest artery of the body?
Aorta Anatomy
The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
What is the function of pulmonary veins?
Pulmonary veins: The veins do the opposite job of pulmonary arteries and collects the oxygenated blood and carry it from the lungs back to the heart. The veins merge into larger veins. Each lung has two pulmonary veins that deliver blood to the heart’s top left chamber or atrium.
What is an artery vs vein?
Vein vs Artery.
Veins are closer to the surface of your body, and arteries are deep inside your muscles. The walls of a vein are thinner than an artery. Veins carry blood from your organs and towards your heart. Arteries carry blood away from your heart.
What are the four main types of coronary veins?
The coronary veins return deoxygenated blood from the myocardium back to the right atrium.
…
cardiac veins which drain into the coronary sinus:
- great cardiac vein.
- middle cardiac vein.
- small cardiac vein.
- posterior vein of the left ventricle.
- vein of Marshall (oblique vein of the left atrium)
What does right atrium mean?
Right atrium: one of the four chambers of the heart. The right atrium receives blood low in oxygen from the body and then empties the blood into the right ventricle.
What vein carries deoxygenated?
The heart
| Blood vessel | Function |
|---|---|
| Vena cava | Carries deoxygenated blood from the body back to the heart. |
| Pulmonary artery | Carries deoxygenated blood from the heart to the lungs. |
| Pulmonary vein | Carries oxygenated blood from the lungs to the heart. |
| Aorta | Carries oxygenated blood from the heart around the body. |
What is the function of superior vena cava?
The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
What artery accompanies the great cardiac 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.
What is a pericardial sinus?
The pericardial sinuses are impressions in the pericardial sac formed between the points where great vessels enter it. Pericardial sinus. Posterior wall of the pericardial sac, showing the lines of reflection of the serous pericardium on the great vessels. ( Transverse sinus labeled at center.
Where is the pulmonary vein?
The pulmonary veins are fixed to the pericardium travel alongside the pulmonary arteries. The right superior pulmonary vein passes in front of and a tad below the pulmonary artery at the root of the lung, and the inferior pulmonary vein is situated at the lowest part of the lung hilum.
Which side of the heart pumps blood to the lungs?
The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries.
Which blood vessel has the highest systolic blood pressure?
As shown in the figure, the aorta and arteries have the highest pressure.
What controls the blood flow?
Blood flow through the body is regulated by the size of blood vessels, by the action of smooth muscle, by one-way valves, and by the fluid pressure of the blood itself.
What is the superior heart chamber?
The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.
Why is the heart on the left side?
This is because the heart’s bottom-left chamber (the ‘left ventricle’) is responsible for pumping oxygenated blood around the whole body, so it needs to be stronger and larger than the right ventricle, which only pumps blood to the lungs. It’s this left ventricle that you can feel beating in your chest.
What is inside your heart?
Inside the Heart
The heart is a four-chambered, hollow organ. … The right and left sides of the heart are further divided into: Two atria – top chambers, which receive blood from the veins and. Two ventricles – bottom chambers, which pump blood into the arteries.
