Quizplus · Accepted Answer

Carbon dioxide is not transported in the blood as a gas, as it is not very soluble in water and would not be able to dissolve and travel in high enough concentrations to meet the body's needs. Instead, it is converted into bicarbonate ions and transported this way, as well as being carried in the blood attached to hemoglobin and dissolved in plasma to a lesser extent.
