In this short video we explain the difference between #Ischemia and #Hypoxia .
Ischemia is in fact an obstruction of #blood flow. Hypoxia is the state of lack of oxygen.
Therefore in Ischemia not only aerobic metabolism is restricted but also anaerobic glycolysis gets compromised after a while once we run out of the already existing substrates or due to the accumulation of metabolites that have to be cleaned away by blood flow.
In hypoxia energy production continues via anaerobic glycolysis, unlike ischemia in which delivery of substrates for glycolysis is compromised.
Ischemia causes more severe injury.
Hypoxia can be caused by blood flow obstruction as well as other causes like insufficient hemoglobin.
