Respiratory system - Diffusion and transport of carbon dioxide (CO2)

3 important questions on Respiratory system - Diffusion and transport of carbon dioxide (CO2)

What is the blood entering the lung capillaries full of?

Carbon dioxide

In which form is most of the carbon dioxide dissolved in the plasma?

either in the form of sodium bicarbonate or carbonic acid. (a little is transported by the red blood cells)
