HESI A2 Heart with 100%
correct answers 2025
Walls of the heart - answer Epicardium=Outer Layer
Myocardium=Middle Layer
Endocardium= Inner Layer
Pulmonary Blood Circuit - answer Right ventricle->Lungs->Left
Ventricle
Systemic Blood Circuit - answer Left Ventricle->Body-> Right Atrium
Full Blood Flow - answer Vena Cava->Right Atrium ->Right Ventricle-
>Pulmonary Artery->Lungs->Pulmonary Veins->Left Atrium-> Left
Ventricle->Aorta->Body
Blood Supply to the Heart - answer Left Coronary Artery supplies
blood to left heart wall
Right Coronary Artery supplies blood to right heart wall
Heart conduction system - answer SA Node->AV Node->Bundle of
His->Bundle Branches->Purkinje Fibers
Systole - answer Contraction Phase
Depolarization and contraction of the ventricles
This is when the blood is pumped into the systemic and pulmonary
circulations
Diastole - answer Relaxation Phase
Repolarization and refilling of the ventricles
