ENTRANCE VALVE THAT SEES ONLY OXYGENATED BLOOD | BICUSPID VALVE |
VALVE THAT PREVENTS THE BACKFLOW OF BLOOD FROM THE LEFT VENTRICLE | BICUSPID VALVE |
HEART SOUND CREATED BY THE CLOSURE OF THE SEMILUNAR VALVES AT THE BEGINNING OF VENTRICULAR RELAXATION | S2 |
EXIT VALVE THAT SEES ONLY UNOXYGENATED BLOOD | PULMONIC VALVE |
VALVE THAT PREVENTS THE BACKFLOW OF BLOOD FROM THE PULMONARY ARTERY | PULMONIC VALVE |
SEMILUNAR VALVE THROUGH WHICH BLOOD LEAVES THE LEFT VENTRICLE | AORTIC VALVE |
ABNORMAL HEART SOUNDS CAUSED BY VALVULAR DISEASE | MURMURS |
ENTRANCE VALVE THAT SEES ONLY UNOXYGENATED BLOOD | TRICUSPID VALVE |

PACEMAKER OF THE HEART | SA NODE |
SPECIALIZED CONDUCTION TISSUE IN THE INTERVENTRICULAR SEPTUM; DIVIDES INTO THE RIGHT AND LEFT BRANCHES | BUNDLE OF HIS |
PLACE WHERE THE ELECTRICAL SIGNAL NORMALLY ARISES | SA NODE |
THE ELECTRICAL SIGNAL SPREADS FROM THE CONDUCTION TISSUE IN THE ATRIA TO THIS STRUCTURE | AV NODE |
AREA OUTSIDE THE SA NODE THAT GIVES RISE TO AN ELECTIRCAL SIGNAL | ECTOPIC FOCUS |
THESE FAST-CONDUCTING FIBERS SPREAD THE ELECTRICAL SIGNAL THROUGHOUT THE VENTRICULAR WALL | PURKINJE FIBERS |
