Final Answer:
pulmonary artery — top-left large blue vessel leaving right ventricle
pulmonary vein — red vessels entering left atrium (upper left side)
aorta — large red vessel arching from top of left ventricle
left ventricle — thick-walled lower-left chamber (dark red)
right ventricle — thinner-walled lower-right chamber (blue)
left atrium — upper-left chamber (light red)
right atrium — upper-right chamber (light blue)
vena cava — large blue vessel entering right atrium (top-right and bottom-right)
semi-lunar valve — between right ventricle & pulmonary artery, and between left ventricle & aorta
(a)–(iii), (b)–(ii), (c)–(iv), (d)–(i)
