The document provides an introduction to pathology, discussing cell adaptation, injury, and death. It defines pathology and outlines its main divisions. It then defines homeostasis, cellular adaptation, and the six types of adaptive responses cells may undergo. It further defines reversible and irreversible cell injury, the phases and mechanisms of injury, and the morphologic changes that can occur during injury and cell death, including apoptosis and the different types of necrosis.
