Spiral bundles of cardiac muscle cells

QRS complex

Ventricular depolarization

Epicardium

Another name for the visceral layer of the serous pericardium

Pulmonary circuit

Right side of the heart is the pump for ——

T wave

Ventricular repolarization

Visceral layer

External surface of the heart

AV node

Delays the impulse from the SA node for 0.1 seconds

P wave

Depolarization of SA node

Superior vena cava

Received the deoxygenated blood from above the heart

SA node

Peacemaker of the heart

Inferior vena cava

Receives the deoxygenated blood from below the heart

Coronary sinus

Receives the deoxygenated blood from the heart itself

Endocardium

Continuous with Endoelialnlining of blood

diastole

Systemic circuit

Left side of the heart is the pump for the ——-

Perietal layer

Lines the internal surface of the fibrous pericardium

Contraction of the heart

Because it’s at the same time as ventricle depolarization
