Answer 1

Pulmonary artery is a type of blood vessel which carry impure blood from heart to the lungs... To oxygenate it..

Pulmonary vein is a type of blood vessel which carries oxygenated blood from lung back to the heart (double circulation).... And then pumped to entire body....

Vena cava is the largest vein of our body... Superior vena cava carried deoxygenated blood coming from upper part of body... And inferior vena cava carries deoxygenated blood coming from lower part of the body....

Aorta.. Is the largest artery of human body... It carries oxygenated blood and supply to the entire body by distributing into smaller arteries and then capillaries.....

Note: artery always carry oxygenated blood and veins always carry deoxygented blood... But pulmonary artery and vein are exception to the same....

Hope it helps buddy....
