Coronary Circulation Flashcards
What do the left and right coronary arteries arise from
Ascending aorta
What does the right coronary artery supply
Conducting systems of the heart
Right atrium
Right ventricle
Part of the left ventricle
Part of the interventricular septum
What are the main branches of the right coronary artery
Branches of the sinoatrial node and atrioventricular node
Right marginal artery
Posterior interventricular artery
What does the right marginal artery supply
Inferior border of the heart
Where does the posterior interventricular artery supply
On inferior (diaphragmatic) surface of the heart
Runs posterior interventricular sulcus
What does the posterior interventricular artery
Supplies both ventricles
What does the left ventricles supply
Conducting systems of the heart
Left atrium
Most of the left ventricle
Part of the right ventricle
Part of the interventricular septum
What are the two terminal branches of the left coronary artery
Anterior interventricular artery
Circumflex artery
What is the left coronary artery called before it divides into terminal branches
Left main stem
What are the main branches of the left coronary artery
Anterior interventricular artery
Diagonal branches
Circumflex artery
Left marginal artery
Where does the circumflex artery run onto
Inferior diaphragmatic surface
What does the circumflex artery supply
Left atrium
Part of the right ventricle
Part of the left ventricle
Where does the left marginal artery arise from
Circumflex artery
What does the left marginal artery supply
Left ventricle
What does the posterior interventricular artery supply
Significant proportion of the left ventricle
