Pulmonary Vein: Transports oxygenated blood from the lungs to the heart’s left atrium

Septum: Divides the right and left sections of the heart

Vena Cavas: The two main veins that return deoxygenated blood to the heart. The superior vena cava returns blood from the upper body, and the inferior vena cava returns blood from the lower body.

Pulmonary Artery: Carries deoxygenated blood from the right ventricle to the lungs

Aorta: The main artery in the body; Receives oxygenated blood from the left ventricle

Right Atrium: Receives spent blood from the veins

Aortic Valve: Located between the left ventricle of the heart and the aorta; Connects the heart to the circulation system of the body

Mitral (Bicuspid) Valve: Located between the left atrium and ventricle; Controls blood flow between these two chambers

Pulmonary Valve: Located between the heart and the lungs; Controls blood flow between the right ventricle and the lungs

Tricuspid Valve: Located between the right atrium and ventricle; Controls blood flow between these two chambers

Left Ventricle: Pumps oxygenated blood throughout the body

Left Atrium: Receives oxygenated blood from the arteries

Right Ventricle: Pumps spent blood to the lungs to be oxygenated
