pathway of blood

Superior and Inferior Vena Cava

Veins through which deoxygenated blood enters the right atrium.

Right Atrium

Chamber where blood accumulates before being pushed through the tricuspid valve.

Tricuspid Valve

One-way valve that prevents backflow of blood into the right atrium.

Right Ventricle

Chamber that contracts to push deoxygenated blood towards the lungs.

Pulmonary Valve

Valve that allows blood to flow from the right ventricle into the pulmonary artery.

Pulmonary Artery

Artery that carries deoxygenated blood to the lungs for oxygenation.

Pulmonary Veins

Veins through which oxygenated blood returns to the heart from the lungs.

Left Atrium

Chamber where blood travels from the pulmonary veins before entering the left ventricle.

Mitral Valve (Bicuspid Valve)

One-way valve that allows oxygenated blood to enter the left ventricle.

Left Ventricle

Thickest chamber that pumps oxygenated blood through the rest of the body.

Aortic Valve

Valve that enables blood to flow from the left ventricle into the aorta.

Aorta

Largest artery that carries oxygenated blood to all parts of the body.
