The document summarizes the transportation of carbon dioxide in the body. It states that 90% of carbon dioxide diffuses into red blood cells, while 7% remains dissolved in the blood plasma. It then lists the three main ways carbon dioxide is transported in the blood: as bicarbonate ions (70%), dissolved in plasma forming carbonic acid (7%), and combined with hemoglobin as carbaminohemoglobin (23%). It concludes by outlining the 9 step process of how carbon dioxide is converted and transported from tissues to the lungs to be exhaled.
