A condition in which there is oxygen deficiency in a habitat or a body part.
In a body part, hypoxia results when the oxygen is below physiological levels in spite of adequate blood perfusion. For instance, the brain receiving inadequate amounts of oxygen causes a cascade of events that may eventually harm the cells and tissues of brain.
