Definitions:

Bohr Effect

Named for Danish physiologist Christian Bohr (1855–1911). Shift of the oxygen-hemoglobin dissociation curve to the right or left because of changes in blood pH. The definition sometimes is extended to include shifts caused by changes in blood carbon dioxide levels.

Oxygen-Hemoglobin Dissociation Curve

A graph showing the relationship between the oxygen saturation of hemoglobin and the partial pressure of oxygen in the blood.

pH

A scale used to specify the acidity or basicity of an aqueous solution, ranging from 0 to 14, where 7 is neutral.

Bicarbonate Ion

A crucial buffer ion (HCO3-) in the blood, responsible for maintaining the body's acid-base balance, it is also involved in transporting carbon dioxide out of tissues.
