Describe the relationship between perfusion, ischemia, infarction, and necrosis
What will be an ideal response?
Perfusion refers to the flow of oxygenated blood through a tissue. Ischemia results when there is too little perfusion, causing an oxygen deficit. Infarction is complete lack of perfusion and a complete lack of oxygen. Necrosis, or tissue death, results from a period of oxygen starvation due to no perfusion.
