1 Superior vena cava. 2 Inferior vena cava. 3 Pulmonary arteries. 4 Pulmonary veins. 5 Aorta.reat vessels is a term used to refer collectively to the large vessels that bring blood to and from the heart.
The right coronary artery and the left coronary artery branch off the aorta (just after it leaves the heart) to deliver oxygen-rich blood to the heart muscle. These two arteries branch into other arteries, including the circumflex artery, that also supply blood to the heart. The cardiac veins collect blood from the heart muscle and empty it into a large vein on the back surface of the heart called the coronary sinus, which returns the blood to the right atrium. Blood Supply of the Heart. Like all organs, the heart needs a constant supply of oxygen-rich blood. A system of arteries and veins, called the coronary circulation, supplies the heart muscle (myocardium) with oxygen-rich blood and then returns oxygen-depleted The two main coronary arteries are the left main and right coronary arteries. Left main coronary artery (LMCA). The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium). Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function, and oxygen-depleted blood must be carried away. The coronary arteries run along the outside of the heart and have small branches that dive into the heart muscle to bring it blood. Great vessels is a term used to refer collectively to the large vessels that bring blood to and from the heart. These are: 1  Superior vena cava. 2  Inferior vena cava. 3  Pulmonary arteries. 4  Pulmonary veins. 5  Aorta.  THE CORONARY VESSELS OF THE HEART Not only does the heart supply the body with blood, but it also supplies blood to itself. The coronary vessels provide the heart tissue with blood; the coronary arteries supply blood to the heart tissue while the veins move oxygenated blood from the heart tissue into the right atrium.  The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood. 1  Left Main Coronary Artery. Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins. These include the great cardiac vein, the middle cardiac vein, the small cardiac vein and the anterior cardiac veins.  The coronary arteries take blood to the heart muscle. These are the first arteries to branch off the aorta-the large artery that takes blood to the body from the left ventricle. 1  The right coronary artery mainly supplies the muscle of the right ventricle.  Collateral circulation is a network of tiny blood vessels, and, under normal conditions, not open. When the coronary arteries narrow to the point that blood flow to the heart muscle is limited (coronary artery disease), collateral vessels may enlarge and become active. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood. 1  Left Main Coronary Artery. The two main coronary arteries are the left main and right coronary arteries. Left main coronary artery (LMCA). The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium). The left main coronary divides into branches: The left anterior descending artery, which branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery, which branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the outer side and back of the heart. Right coronary artery (RCA). The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regular the heart rhythm. The two main coronary arteries are the left and right coronary arteries. The left coronary artery (LCA), which divides into the left anterior descending artery and the circumflex branch, supplies blood to the heart ventricles and left atrium.
