PREVENTS BACKFLOW FROM AORTA TO LEFT VENTRICLE
WHAT IS THE PURPOSE OF THE AORTIC SEMILUNAR VALVES
PREVENT BACKFLOW FROM THE AORTA TO THE RIGHT VENTRICLE
WHAT IS THE SHORTEST UNIT OF CIRCULATION IN THE BODY
CORONARY CIRCULATION
FIRST 2 BRANCHES OF THE AORTA
CORONARY ARTERIES
WHAT ARE THE 2 BRANCHES OF THE CORONARY ARTERIES
RIGHT CORONARY ARTERY AND LEFT CORONARY ARTERY
FOLLOWS CORONARY SULCUS AND RUNS TO RIGHT SIDE OF THE HEART
RIGHT CORONARY ARTERY
2 DIVISIONS OF THE RIGHT CORONARY ARTERY
MARGINAL ARTERY AND POSTERIOR INTERVENTRICULAR ARTERY
WHAT DOES THE MARGINAL ARTERY SUPPLY
MYOCARDIUM OF LATERAL PART OF RIGHT SIDE OF HEART
WHAT DOES THE POSTERIOR INTERVENTRICULAR ARTERY SUPPLY
POSTERIOR VENTRICULAR WALLS AND INTERVENTRICULAR SEPTUM
RUNS TOWARD LEFT SIDE OF THE HEART AND DIVIDES INTO 2 BRANCHES
LEFT CORONARY ARTERY
2 DIVISIONS OF THE LEFT CORONARY ARTERY
CIRCUMFLES ARTERY AND ANTERIOR INTERVENTRICULAR ARTERY
WHAT DOES THE ANTERIOR INTERVENTRICULAR ARTERY SUPPLY
LEFT ATRIUM AND INTERVENTRICULAR SEPTRUM AND ANTERIOR WALLS OF BOTH VENTRICLES
THE CIRCUMFLEX ARTERY WILL ALSO BRANCH TO WHAT
LEFT MARGINAL ARTERY
WHAT DOES THE LEFT MARGINAL ARTERY SUPPLY
