Bauxite is the primary ore of aluminum. Almost all of the aluminum that has ever been produced has been extracted from bauxite. The United States has a few small bauxite deposits but at least 99% of the bauxite used in the United States is imported. The United States is also a major importer of aluminum metal. Many people are surprised to learn ...

The first mechanism of carbon dioxide transport is by blood plasma, as some carbon dioxide molecules dissolve in the blood. The second mechanism is transport in the form of bicarbonate (HCO 3– ), which also dissolves in plasma. The third mechanism of carbon dioxide transport is similar to the transport of oxygen by erythrocytes ( Figure 22.5.4 ).
