When this chamber contracts it pushes blood through the tricuspid valve

• Vena Cava

When blood leaves the heart, it heads to the lungs through the

• Pulmonary trunk

• Aorta

• Inferior Vena Cava

• Superior Vena Cava

Stops blood flow from flowing back into the ventricles each time they contract.

• SA node

• Semilunar Valves

• Tricuspid and bicuspid valves

• Right atrium

Responsible for distributing electrical impulses throughout the heart

This blood vessel splits in two and sends oxygen poor blood to the lungs
