What is the coronary artery in an adult?
There are two, the right and the left. They are the blood vessels that run directly out of the heart. One runs to the lungs to get oxygen and the other sends oxygenated blood into the body. ALSO: THEY ARE THE BLOOD VESSELS THAT SUPPLIES BLOOD TO THE HEART'S MUSCLES ---- The first answer above is incorrect. The coronary arteries are two in number, the right and the left. They arise from the proximal aorta, just after the aortic valve and supply blood directly to the cardiac muscle. The left has three main divisions: the left main coronary artery, which is the relatively short first segment. The left main then branches into the left anterior descending (LAD) and the left circumflex artery. The left artery supplies most of the septum and left side of the heart, including the left ventricle. The right coronary artery is a relatively smaller vessel and supplies the right side of the heart and the inferoposterior portion of the heart. It also supplies blood to the SA node and also to the AV node (in about 60% of patients).
What major artery supplies the heart itself blood?
The coronary arteries. These leave the aorta and branch out over the heart. Blood only flows though these vessels during diastole because during systole they are blocked off by the aortic valve. The two main vessels that arise from the Sinus of Valsalva, located just above the aortic valves, are the right and left cornary arteries. The right coronary artery mainly supply the right ventricle and the sinoatrial node. The left main artery is divided into the left anterior descending artery and the left circumflex artery. The left anterior descending artery mainly supplies the anterior and septal portion of the heart, namely the left ventricle. The left circumflex artery supplies the lateral walls of the left ventricle. Finally, the posterior descending artery can arise from either the right or left coronary artery. If the posterior descending artery arises from the right coronary artery, the heart is termed right heart dominant, which is seen in approximately 70% of individuals. If the posterior descending artery arises from the left circumflex artery, it is termed left heart dominance. It is also possible for the posterior descending artery to arise from both the right and left coronary artery. In this configuration, the heart is considered co-dominant. The posterior descending artery mainly supplies the inferior wall of the left ventricle and the inferior portion of the septal wall.
What cardiac structures does the right coronary artery supply?
SA node A portion of the inferior/posterior surface of the left ventricle Right ventricle AV node Bundle of HIS
How does the heart receive it's blood supply?
Located just above the aortic valves, are the right and left cornary arteries. The right coronary artery mainly supply the right ventricle and the sinoatrial node. The left main artery is divided into the left anterior descending artery and the left circumflex artery. The left anterior descending artery mainly supplies the anterior and septal portion of the heart, namely the left ventricle. The left circumflex artery supplies the lateral walls of the left ventricle.
What circulatory system supplies the heart with blood?
Through it's own network of arteries in the heart itself. These are the arteries that are disrupted during a heart attack, and they are also bypassed during a bypass surgery with veins from the legs.

What blood vessel gives rise to the marginal artery and posterior interventricular artery?
They branch off from the right coronary artery which arises from the aorta.
What cardiac structures does the right coronary artery supply?
SA node A portion of the inferior/posterior surface of the left ventricle Right ventricle AV node Bundle of HIS
Artery that supplies blood to the heart wall?

What causes junctional tachycardia?
Most commonly it is due to digitalis toxicity...sometime it may be due to AV node block or coronary artery disease. Juctional tachycardia may be precipitated by Hyperkalemia in a patient with conduction system disease.
What is para aortic prominent lymph node?
A paraaortic prominent lymph node is a lymph node more noticable than the others and found near the aorta.
Inferior wall ischemia?
An inferior wall mycardial infarction is a heart attack involving the inferior portion of the left ventricle, and in many cases the right ventricle. This is caused by occlusion of the right coronary artery. This can also indicate ischemia (poor oxygenation) of the AV node and bundle of HIS, as these structures are also supplied by the right coronary. An inferior wall MI can be seen in the inferior leads II, III, and AVF.
How are The left and right coronary arteries carry oxygenated blood from the base of the aorta to the heart muscle and the aorta?
The LCA travels through the coronary sulcus under the left auricle & divides into2 branches: anterior interventricular branch & the circumflex branch The RCA supplies the Right Atrium & the sinotrial node, continues along the coronary sulcus under the right auricle, & gives off 2 branches: Right Marginal branch & Posterior interventricular branch Arteries carry deoxygenated blood
What are the blood vessels are linked directly to the heart called?
superior vena cava(biggest vein coming from chest, head, and upper extremities)inferior vena cava(biggest vein coming from abdomen and lower extremities)aorta(biggest artery)
