Function: noun
: the decrease in oxygen affinity of a respiratory pigment (as hemoglobin orhemocyanin) in response to decreased blood pH resulting from increased carbon dioxide concentration
Bohr, Christian (1855–1911) Danish physiologist. Bohr is known for twocontributions to medical science: an 1891 study of the exchange of gases in respiration and the discovery that the affinity of blood for oxygen depends on carbon dioxide pressure. This discovery wasreported in 1904 and is now known as the Bohr effect.
