The majority of carbon dioxide produced by our body cells is transported to the lungs:

Step-by-step solution

Carbon dioxide molecules are transported in the blood from body tissues to the lungs by one of three methods: dissolution directly into the blood, binding to haemoglobin, or carried as a bicarbonate ion. About 5 to 7 percent of all carbon dioxide is dissolved in the plasma. About 10 percent of carbon dioxide can bind to plasma proteins or can enter red blood cells and bi nd to hemoglobin to form carbaminohemoglobin. The majority of carbon dioxide molecules ( 85 percent) are carried as part of the bicarbonate buffer
