Atrium
Left connects to the lungs
Right connects to the veins
Ventricles
Left connects to the aorta
Right connect to the pulmonary artery
Valves
Controls the blood flow between the chambers and to major blood vessels.
Permits movement to flow in only one direction
Tricuspid Valve
Separates the right atrium and the right ventricle
Mitral Valve
Separates the left atrium and the left ventricle
Pulmonary Artery
Permits blood to flow into the pulmonary artery from the right ventricle
Aortic valve
Permits blood to flow into the aorta from the left ventricle
Arteries
Responsible for carrying blood away from the heart
Veins
Responsible for returning blood back to the heart
Pulmonary Circulation
Moves blood to the lungs to pick up oxygen and back to the heart so it can deliver oxygenated blood
Systemic Ciruclation
Pumps oxygen rich blood to the body and returns deoxygenated blood to the heart for refueling.
Aorta
Carries oxygenated blood from the left ventricle to the rest of the body,
Superior Vena Cava
Returns blood back to the right atrium from the upper half of the body
Inferior Vena Cava
Returns blood back to the right atrium from body parts below the diaphragm.
Coronary artery
Blood vessels supply oxygen to the heart tissues
Apex
Bottom of the heart where it comes to a point.
Left Ventricle
Responsible for pumping oxygenated blood to tissues all of the body
Right Ventricle
Receives deoxygenated blood from the right atrium and pumps it to the lungs
Auricles
The ear-like extensions of the atria.
Left atrium
Chamber that receives oxygenated blood from the lungs.
Right atrium
Chamber that receives deoxygenated blood from the vena cava.
Brachiocephalic artery
A major artery that branches from the arch of the aorta
Pulmonary veins
The blood vessels that carry oxygenated blood from the lungs to the left atrium.
Chordae tendinae
Fibrous chords that attach to the tricuspid and mitral valves.
Papillary muscle
Muscles that attach the cusp of the tricuspid and mitral valve by choradae tendinae
