Physiology
In 1891, he was the first to characterize the physiological dead space in pulmonary respiration, i.e., the inhaled air volume not involved in gas exchange.
In 1904, Christian Bohr described the phenomenon, now called the Bohr effect, whereby hydrogen ions ( H+) and carbon dioxide (CO2) heterotopically decrease hemoglobin's oxygen-binding affinity. This regulation increases the efficiency of oxygen release by hemoglobin in tissues, like active muscle tissue, where rapid metabolization has produced relatively high concentrations of H+ and CO2.
