Coronary circulation Flashcards
where do the left and right coronary arteries arise from
aorta
The left coronary artery divides into 2 branches what are they
The anterior interventricular artery
The circumflex artery
The anterior interventricular artery is known clinically as
the left anterior descending artery
The anterior interventricular artery follows the
anterior interventricular sulcus
The anterior interventricular artery provides blood for what
to the interventricular septum and anterior walls of both ventricles.
The circumflex artery supplies the
left atrium and the posterior walls of the left ventricle.
The right coronary artery courses to the right side of the heart, where it also gives rise to two branches.
The right marginal artery
The posterior interventricular artery
The right marginal artery serves the
myocardium of the lateral right side of the heart.
The posterior interventricular artery runs to the heart ____and supplies the __________. Near the apex of the heart, this artery merges (anastomoses) with the ___________
apex
posterior ventricular walls
anterior interventricular artery
Together the branches of the right coronary artery supply the _______ and nearly all the _______
right atrium
right ventricle
After passing through the capillary beds of the myocardium, the venous blood is collected by the
cardiac veins
the cardiac veins join to form an enlarged vessel called the _________-, which empties the blood into the________.
coronary sinus
right atrium
The sinus has three large tributaries: the ____ cardiac vein in the anterior interventricular sulcus; the ____ cardiac vein in the posterior interventricular sulcus; and the _____ cardiac vein, running along the heart’s right inferior margin. Additionally, several anterior cardiac veins empty directly into the_________ anteriorly.
great cardiac vein
middle cardiac vein
small cardiac vein
right atrium
