WebCarbon 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 hemoglobin, or carried as a bicarbonate ion. Several properties of carbon dioxide in the blood affect its transport. First, carbon dioxide is more soluble in blood than oxygen. WebCarbon dioxide will diffuse into the plasma and react with water to produce carbonic acid. Carbonic acid will then dissociate into hydrogen ions and hydrogencarbonate ions. The hydrogen ions combine with haemoglobin to form haemoglobinic acid.
