Chambers: Hollow spaces for blood

Valves: Keep a one way flow of blood. Ex: Ventricular contraction - Tricuspid and Mitral valves close, Pulmonary and Aortic valves open

Arteries: Carry blood away from the heart

Veins: Carry blood back to the heart

Papillary muscles: Control the action of the Chordae Tendonae

Chordae Tendonae: “Strings” that open and close the valves

The Tricuspid valve and Bicuspid (Mitral Valves) are called Atrioventricular Valves (AV Valves) because they divide the atria from the ventricles

The Aortic valve controls the flow of blood into the aorta

The Pulmonary valve controls the flow of blood into the Pulmonary Trunk

Regurgitation refers to the valves not closing properly and allowing a backflow of blood

Stenosis refers to a stiffening or narrowing of the valve preventing it from opening fully.

Pulmonary Circulation: Carries deoxygenated blood from the heart to the lungs for oxygenation and returns oxygenated blood to the heart.

Systemic Circulation: moves oxygenated blood from the heart to the body and deoxygenated blood back to the heart
