QuestionSBA
QuestionChoice
This image shows a view of the coronary arteries of the heart as they emerge from the ascending aorta. This answer describes the function of the posterior interventricular artery (also termed posterior descending artery), a branch of the right coronary artery, which supplies the posterior one third of the interventricular septum and adjacent areas of the left and right ventricles. However, the arrow points to the right coronary artery. The function of the right coronary artery is to supply blood to the right atrium and ventricle, as well as to the sinoatrial and atrioventricular nodes of the conducting system of the heart (in most people).

e
Supplies blood to the interventricular and inferior aspects of the heart
QuestionChoice
This image shows a view of the coronary arteries of the heart as they emerge from the ascending aorta. The answer describes the function of the left coronary artery – to supply blood to the left atrium and ventricle. However, the arrow points to the right coronary artery. The function of the right coronary artery is to supply blood to the right atrium and ventricle, as well as to the sinoatrial and atrioventricular nodes of the conducting system of the heart (in most people).

b
Supplies blood to the left atrium and ventricle
QuestionChoice
This image shows a view of the coronary arteries of the heart as they emerge from the ascending aorta. The answer describes the function of the left anterior descending artery, a main branch of the left coronary artery, which supplies the anterior surface of the left ventricle and the distal two thirds of the interventricular septum. The function of the right coronary artery is to supply blood to the right atrium and ventricle, as well as to the sinoatrial and atrioventricular nodes of the conducting system of the heart (in most people).

d
Supplies blood to the left anterior aspect of the heart
QuestionChoice
This image shows a view of the coronary arteries of the heart as they emerge from the ascending aorta. The arrow points to the right coronary artery, which supplies. blood to the right atrium and ventricle, as well as to the sinoatrial and atrioventricular nodes in most people. (N.B. the right coronary artery supplies the SA node in approximately 60% of people and the AV node in approximately 80% of people).

a
Supplies blood to the right atrium and ventricle, and to the sinoatrial and atrioventricular nodes
QuestionChoice
This image shows a view of the coronary arteries of the heart as they emerge from the ascending aorta. The answer describes the function of the circumflex artery, a branch of the left coronary artery, which supplies the left atrium and left ventricle. The arrow points to the right coronary artery. The function of the right coronary artery is to supply blood to the right atrium and ventricle, as well as to the sinoatrial and atrioventricular nodes of the conducting system of the heart (in most people).
