PATHOLOGY

Detailed explanation-1: -Acute cell swelling is the classic morphologic change in reversible injury; however, it is also the typical early change of irreversible cell injury. Irrespective of the nature of the initial injury, hypoxia is often the ultimate cause of acute cell swelling because it results in adenosine triphosphate depletion.

Detailed explanation-2: -There are three major types of morphologically distinct cell death: apoptosis (type I cell death), autophagic cell death (type II), and necrosis (type III). All three can be executed through distinct, and sometimes overlapping, signaling pathways that are engaged in response to specific stimuli.
