Term Name:	response to hypoxia		Search Ontology:
Synonyms:	response to hypoxic stress response to intermittent hypoxia response to lowered oxygen tension response to sustained hypoxia
Definition:	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level.
