Presented by Kami Dykes • What are the four chambers of the heart? right atrium, left atrium, right ventricle, left ventricle • What are the four valves of the heart? tricuspid valve, bicuspid valve, pulmonary valve, aortic valve • What are the five major vessels of the heart? Superior vena cava, inferior vena cava, pulmonary arteries, pulmonary veins, aorta Aorta Superior vena cava Pulmonary valve R. Pulmonary artery Branches of R. pulmonary vein R. atrium Tricuspid valve R. ventricle Inferior vena cava Pulmonary artery Pulmonary trunk L.

Arteries carry blood away from the heart while veins carry blood into the heart. The vessels colored blue indicate the transport of blood with relatively low content of oxygen and high content of carbon dioxide. The vessels colored red indicate the transport of blood with relatively high content of oxygen and low content of carbon dioxide.
