Introduction to Cell injury 

Cell injury underlies all diseases. So to understand diseases one, has to start by knowing what cell injury is. When a cell is exposed to an injurious agent (i.e. the causes of diseases discussed in chapter one), the possible outcomes are:

1.  The cell may adapt to the situation or

2.  They cell may acquire a reversible injury or

3.  The cell may obtain an irreversible injury & may die. The cell may die via one of two ways: either by necrosis or by apoptosis.

Which of these outcomes occur depends on both the injurious agent & on cellular factors. In other words, the result depends on the type, severity, & duration of the injury & on the type of the cell.
