Cell injuries could occur as a process that is reversible or as one which is not reversible called Irreversible Cell Injury. A cell injury that is reversible is one in which the cells can go back to their normal function. Irreversible Cell Injury inevitably results in the death of the cells, which could also be called necrosis of the tissues. Both kinds of cell injury signify a noxious stimulus around the environment on the cell. The factors responsible for the distinguishing between Reversible and Irreversible Cell Injury are duration or period of the injury and the kind or type of injury.
Reversible cell injury would result in swelling, which would be very obvious and increment in the surface area around the tissue levels. While for irreversible Cell Injury, there would be the death of the cell and necrosis of the tissue. Reversible cell injury can actually be treated, but irreversible Cell Injury cannot be treated and ultimately would lead o loss of the cell.
