How is most carbon dioxide transported from tissues to the lungs? view available hint(s) how is most carbon dioxide transported from tissues to the lungs? as carbonic acid. as carbon dioxide gas. as bicarbonate ions (hco3−). as protons (h+)?

Most carbon dioxide is transported from tissues to the lungs  as a bicarbonate ions(HCO3-) in the plasma. Carbon dioxide is transported in the blood from the tissues to the lungs in three different ways. some of it is transported dissolved in the plasma, some is transported as carbaminohemoglobin and other as bound to proteins. However most carbon dioxide is transported as bicarbonate; as blood flows through the tissues, carbon dioxide diffuses into red blood cells, where it is converted into bicarbonate.
