What is the function of right coronary artery?
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. The right coronary artery divides into smaller branches, including the right posterior descending artery and the acute marginal artery.
What does the marginal artery supply?
The marginal branch of the right coronary artery provides blood supply to the lateral portion of the right ventricle. The posterior descending artery branch supplies blood to the inferior aspect of the heart. The LMCA supplies blood to the left side of the heart.
Where are posterolateral branches located?
The left ventricular branches of the RCA are known as the posterolateral branches. These branches extend to the adjacent portion of the left ventricle and arise at right angles from the posterior descending artery.
Which coronary artery is most important?
The heart’s three coronary arteries are not all equal. The most important artery is called the left anterior descending artery (LAD). It feeds blood to the whole front wall of the heart, which represents much more muscle than the area fed by either of the other two coronary arteries.
What coronary artery supplies the inferior wall?
right coronary artery
The right coronary artery supplies blood to the right ventricle and then supplies the underside (inferior wall) and backside (posterior wall) of the left ventricle.
What is the marginal artery heart?
The right marginal artery is a branch of the right coronary artery. It supplies the majority of the myocardium of the right ventricle of the heart. Some authors refer to this artery as the acute marginal artery, or the right marginal branch of right coronary artery.
Where is the posterior descending artery located?
The rest of the right coronary artery and its main branch, the posterior descending artery, together with the branches of the circumflex artery, run across the surface of the heart’s underside, supplying the bottom portion of the left ventricle and back of the septum.
Where is the mid circumflex?
Location: The circumflex artery branches off of the left coronary artery and supplies most of the left atrium: the posterior and lateral free walls of the left ventricle, and part of the anterior papillary muscle.
