The major fraction of ${\mathrm{CO}}_2$ released during cellular
respiration is transported by the blood to the lung capillaries 

Or

Approximately seventy percent of carbon-dioxide absorbed by the blood will be transported to the lungs

In the given graph curves $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ represent the relation between partial pressure of oxygen $\left({\mathrm{pO}}_2\right)$ and saturation of haemoglobin with oxygen. If curve $\mathrm{A}$ represents the condition of blood in a regular artery then please select the correct statement from below.

Select the favourable conditions required for the formation of oxyhaemoglobin at the alveoli.

Study the following forms of transport of respiratory gases
A) ${\mathrm{CO}}_2$ as bicarbonates
B) ${\mathrm{O}}_2$ through plasma
C) ${\mathrm{CO}}_2$ as carbamino compounds
D) ${\mathrm{O}}_2$ through $\mathrm{RBC}$
E) ${\mathrm{CO}}_2$ in a dissolved state
Arrange the above in sequence in ascending order based on their percentages.
