Which among the the following carries impure blood to human heart ?

Options

A. Aorta
B. Pulmonary vein
C. Pulmonary arteries
D. Vena Cava

Answer

C

Explanation

A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs . The pulmonary arteries are unique in that unlike most arteries which carry oxygenated blood to other parts of the body , the pulmonary arteries carry de- oxygenated blood to the lungs . After picking up oxygen , the oxygen rich blood is returned to the heart via the pulmonary veins.
