It then curves around the left margin of the heart to reach the posterior surface. It merges with the oblique vein of the left atrium to form the coronary sinus, which drains into the right atrium. At the junction of the great cardiac vein and the coronary sinus, there is typically a valve present. Great cardiac vein. 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. The great cardiac vein commonly continues until it merges with the coronary sinus . The lateral veins, also known as the left marginal veins or the obtuse marginal veins, course along the left side of the heart and drain the left ventricular myocardium into the great cardiac vein or coronary sinus . The right atrium receives and holds deoxygenated blood from the superior vena cava, inferior vena cava, anterior cardiac veins and smallest cardiac veins and the coronary sinus, which it then sends down to the right ventricle (through the tricuspid valve), which in turn sends it to the pulmonary artery for pulmonary
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.
It then curves around the left margin of the heart to reach the posterior surface. It merges with the oblique vein of the left atrium to form the coronary sinus, which drains into the right atrium. At the junction of the great cardiac vein and the coronary sinus, there is typically a valve present.
The middle cardiac vein or posterior interventricular vein is a vein of the heart which accompanies the posterior interventricular artery. It drains the posterior wall of both ventricles and the posterior interventricular septum.
The small cardiac vein runs in the coronary sulcus between the right atrium and ventricle and opens into the right extremity of the coronary sinus. It receives blood from the posterior portion of the right atrium and ventricle. It may drain to the coronary sinus, right atrium, middle cardiac vein, or be absent.
The great saphenous vein is a large venous blood vessel running near the inside surface of the leg from the ankle to the groin. The purpose of the great vein is delivery of blood from the ankle, lower leg, and thigh to the femoral vein.
anterior interventricular branch of left coronary artery
The internal jugular vein is a major blood vessel that drains blood from important body organs and parts, such as the brain, face, and neck. These veins functions to carry oxygen-depleted blood from the brain, face, and neck, and transport it to the heart through the superior vena cava.
Coronary venous anatomy is highly variable, but is generally comprised of three groups: cardiac veins which drain into the coronary sinus: great cardiac vein. middle cardiac vein.
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).
The myocardium drains mainly by two groups of veins: the tribu- taries of the greater and smaller cardiac veins, or the Thebesian veins. The main vein of the greater venous system is the CS that runs in the posterior aspect of the coronary groove.
The Coronary Arteries are the blood vessels that supply blood to your heart. They branch off of the aorta at its base. The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries.
The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm. Together with the left anterior descending artery, the right coronary artery helps supply blood to the middle or septum of the heart.
Coronary circulation, part of the systemic circulatory system that supplies blood to and provides drainage from the tissues of the heart. Deoxygenated blood is returned to the chambers of the heart via coronary veins; most of these converge to form the coronary venous sinus, which drains into the right atrium.
Despite carrying oxygenated blood, this great vessel is still considered a vein because it carries blood towards the heart. Four pulmonary veins enter the left atrium. The right pulmonary veins pass behind the right atrium and superior vena cava while the left pass in front of the descending thoracic aorta.
