<prompt> C02 is primarily transpoed in the aerial blood as:Dissolved C02Carbonic AcidCarbamino-hemoglobinBicarbonate  <response>: Transpo of carbon dioxide in the form of bicarbonate ions accounts for approximately 70 of the carbon dioxide transpoed from the tissues to the lungs. Thus this is by far the most impoant of all methods of transpo. Ref: Textbook of Medical Physiology By Guyton, 10th Edition, Page 471
