• capillaries

• arteries

• atrium

• arteries

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

• pulmonary veins

• inferior vena cava

• pulmonary trunk

• superior vena cava

This area of the heart initiates the action potential that causes the heart beat

• SA node

• Right Atrium

• AV node

• Left Atrium

One of the largest blood vessels that transports blood from the body region below the diaphragm to the heart

• Pulmonary veins

• Superior Vena Cava

• Aorta

• Inferior Vena Cava

Chamber of the heart that receives oxygenated blood from the lungs
