Answer 1

Answer:

Explanation:

The blood in the body leaves the tissues becomes richer in CO2. The main artery(aorta) carries oxygenated blood from the heart to the organs. when this blood passes through the capillaries of body organs, it gives oxygen to the body cells. At the same time, CO2 produced during respiration enters the blood. Thus deoxygenated blood(carrying CO2) leaves tissues and enters vena cava, from where they are again passed to the lungs for oxygenation.

So the correct option is 'CO2'.
