Answer 1

it is A) CO2 because the tissue fluid in tissues transfer all waste material (majority co2). 

Answer 2

The ‘blood leaving’ the tissues becomes rich in carbon dioxide.

Option: (a)

Explanation:

• The blood that is left from the tissues is rich in ‘carbon dioxide’. The aorta or the main artery always carries oxygenated blood to all the body organs from the heart.  

• When such oxygenated blood passed through the body capillaries of the organs or tissues, it would give the oxygen to the cells of the body.  

• On the other hand, $\mathrm{CO}_{2}$ produces during the respiration will enter into the blood. Thus the deoxygenated blood leaves the tissue will enter vena cava.
