differentiate between transport O2 and transportCO2

saveral propertries of carbon dioxide in the blood effect its transport
Oxygen is transported from alveoli of lungs via haemoglobin, present in RBC, in oxyhaemogolbin form (i.e. oxygenated blood), to tissue level through the route of arteries.
At tissue level due to difference in partial pressure of oxygen and carbondioxide in between RBCs and cell of tissue, exchange of oxygen and carbondioxide takes. Now, the carbondioxide that the cells gives to RBCs, reacts with its haemoglobin to form deoxyhaemoglobin ( i. e. deoxygenated blood is formed). This deoxygenated blood now goes to alveoli in lungs through veins route.
Again, almost same thing as above happens here that is, due to partial pressure difference between oxygen in alveoli and carbondioxide in deoxyhaemoglobin of RBCs, exchange of oxygen and carbondioxide happens. In this way, the blood is again oxygenated and the CO2 released to alveoli is released out to surrounding.
These all are some difference in transportation of oxygen and carbondioxide.
