Autolysis

Heterolysis

Necrosis

Coagulation (Coagulative) necrosis

2- Adaptation :

Adaptation is the structural and functional changes in cells and tissues to accommodate itself to the changing environment and extra-cellular stress or injury.

3- Cellular Accumulations

When injury is sublethal and sustained, cells and tissues tend to accumulate substances in abnormal quantities.

Accumulation of Glycogen, complex lipids and carbohydrates

Pigments

Melanin

Pigments derived from Hemoproteins

Hemosiderin and Hemosiderosis

Primary Hemochromatosis

Pathologic Calcification

4- Inflammation

Inflammatory cells in acute and chronic inflammation

Acute Inflammation

Types of Acute Inflammation

Chemical Mediators

Chronic Inflammation

5- Wound Healing

6- Hemodynamic Disorders of Perfusion :

Hemodynamic disorders are those diseases that disturb perfusion and result in organ and cellular injury.
