Answer 2

Question:-

Find the odd one and give reason, Pulmonary vein, pulmonary artery, left auricle and left ventricle

Answer:-

The odd one is "Pulmonary artery"

Reason:-

The answer is the "pulmonary artery". The other three all carry oxygenated blood, whereas the pulmonary artery carries deoxygenated blood. The left auricle (atrium is a better term to use) receives oxygenated blood from the lung via the pulmonary vein. The left atrium in turn passes on oxygenated blood to the left ventricle. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs.

So, the odd one is "Pulmonary artery"
