pbs 1.2.5

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
