Your question: What does the middle cardiac vein supply?

The middle cardiac vein drains into the coronary sinus or directly into the right atrium [4]. The small cardiac vein, also known as the right cardiac vein [12], commonly drains the inferior and lateral wall of the right ventricle.

What does the middle cardiac vein do?

Along with the great and small cardiac veins, the middle cardiac vein constitutes the greater cardiac venous system. The function of the middle cardiac vein is to drain the venous blood of the external layer of the myocardium.

What does the small cardiac vein supply?

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.

What does the great cardiac vein supply?

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 does each coronary artery supply?

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.

Where is the middle cardiac vein found?

The middle cardiac vein commences at the apex of the heart; ascends in the posterior longitudinal sulcus, and ends in the coronary sinus near its right extremity.

Where does the middle cardiac vein drain?

The middle cardiac vein drains into the coronary sinus or directly into the right atrium [4]. The small cardiac vein, also known as the right cardiac vein [12], commonly drains the inferior and lateral wall of the right ventricle.

What is the main function of small cardiac vein?

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

How many cardiac veins are there?

It travels along the diaphragmatic aspect of the left ventricle, alongside the middle cardiac vein. Overview of the main coronary arteries and cardiac veins (20 structures).

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 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.

Which side of the heart delivers deoxygenated blood?

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.

What blood vessels drain the heart?

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 coronary artery is most commonly blocked?

Importance in cardiovascular diseases:

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.

Which artery is the widow maker?

The widow-maker is a massive heart attack that occurs when the left anterior descending artery (LAD) is totally or almost completely blocked. The critical blockage in the artery stops, usually a blood clot, stops all the blood flow to the left side of the heart, causing the heart to stop beating normally.

What are the 5 main coronary arteries?

Structure

  • Left coronary artery (LCA) Left anterior descending artery. Left circumflex artery. Posterior descending artery. Ramus or intermediate artery.
  • Right coronary artery (RCA) Right marginal artery. Posterior descending artery.
