This document provides an overview of basic pathology concepts including cell injury, cell death, and various types of necrosis. It discusses how cells attempt to maintain homeostasis but may undergo injury when stressed beyond their adaptive capabilities. The two main types of cell death are necrosis, which occurs from external factors like lack of oxygen, and apoptosis, which is a programmed suicide process. Necrosis can be coagulative, liquefactive, caseous, involving fat or fibrinoid. The document also covers edema, hemorrhage, shock, thrombosis and embolism.
