Takes deoxygenated blood to the lungs

Pulmonary trunk & left/right pulmonary arteries (function)

Returns deoxygenated blood to the right atrium

superior & inferior vena cava (function)

prevents backflow of blood into right atrium

tricuspid valve (function)

holds the tricuspid/bicuspid valve closed during ventricular systole

chordae tendineae (function)

prevents the backflow of blood into the right ventricle

pulmonary valve (function)

Returns oxygenated blood to the left atrium

left and right pulmonary veins (function)

takes oxygenated blood to the entire head/body

Ascending aorta, Aortic arch & Descending aorta (function)

prevents backflow of blood into left atrium

bicuspid valve (function)

holds the tricuspid/bicuspid valve closed during ventricular systole

papillary muscles (function)

prevents the backflow of blood into the left ventricle

aortic valve (function)
