The given figure shows schematic plan of blood
circulation in humans with labels A to D. Identify
the label and give its functions.
(a) C - Vena cava - Takes blood from body parts to
right auricle, pCO2 = 45 mm Hg
(b) D - Dorsal aorta - Takes blood from heart to
body parts, pO2 = 95 mm Hg
(c) A - Pulmonary vein - Takes impure blood from
body parts, pO2 = 60 mm Hg
(d) B - Pulmonary artery - Takes blood from heart
to lungs, pO2 = 90 mm Hg
