I am having a bit of trouble. I am going over cellular injury, from what I am understanding that they are two types of Cellular Injury; Reversible, Irreversible.

Q: What are some causes of Cellular injury?

I would say: Hypoxia, Reperfusion injury????, ROS???? (What is that, what is the difference between ROS and Reprefusion? isn’t this an irreversible injury?) , Physical, Chemical, Unintentional and Intentional, Immunologic, infectious (aren’t they the same?), gene and epigenetics.

What is the difference between between reversible and irreversible, when i mean by that, what happens to the cell that irriversible do that reversible dosen’t. any halmark notes about irreversible like Na+ leaves the cell?
