Dictionary of Biological Psychology
Hypoxia is a decrease in the level of OXYGEN in the BLOOD or tissues below that which is normal.
Anaemic HYPOXIA is caused by a loss of haemoglobin (the oxygen-transporting MOLECULE) form the blood; DIFFUSION hypoxia is caused by a transient decrease in pressure within the lungs (and is rare—it is associated with recovery from ANAESTHESIA); hypoxic HYPOXIA is caused by defective action of the lungs, with a wide variety of possible causes; ischaemic hypoxia (also known as stagnant anoxia) results from reduced blood flow.
