2). PULMONARY VEIN

Answer 2

ANSWER:

1. The vessel that contains the smallest number of ‘red blood cells’ per unit volume of ‘blood’ is the hepatic vein.

2. The vessel that carries oxyhaemoglobin is the pulmonary vein.  

EXPLANATION:  

The hepatic veins are the veins or vessels that are used to carry the ‘deoxygenated blood’ from the liver to the 'inferior vena cava' in order to oxygenate them. The pulmonary vein are the largest vessels that carry the ‘oxygenated blood’ from the lungs to the other parts of the body, they are the only vein that carries 'oxygenated blood'.
