What does necrosis refer to?

Necrosis specifically refers to the process of tissue death, often resulting from factors such as disease, injury, or lack of blood supply. When cells experience necrosis, they undergo a series of changes, leading to irreversible damage and ultimately cell death. The process can be caused by a variety of factors including infections, toxins, inflammation, or trauma. It's important to distinguish necrosis from other terms; for instance, joint inflammation refers to conditions like arthritis, tissue swelling describes an increase in fluid in the tissues, and muscle atrophy is the reduction in muscle mass. The uniqueness of necrosis lies in its direct association with the death of tissue, marking it as a critical concept in understanding various medical conditions and the consequences of cellular injury.
