nekrooitua

Nekrooitua is a Finnish term that translates to "necrosis" in English. Necrosis is a form of cell death that occurs when living cells are subjected to harsh conditions or injury. This can be caused by a variety of factors, including infection, toxins, trauma, or lack of oxygen. Unlike apoptosis, which is a programmed and controlled form of cell death, necrosis is an uncontrolled process that leads to the lysis, or bursting, of the cell.

When a cell undergoes necrosis, its organelles swell and its membrane ruptures, releasing its contents into the surrounding tissue. This can trigger an inflammatory response, as the body attempts to clear away the damaged cellular debris. The specific appearance of necrotic tissue can vary depending on the cause and the type of tissue affected. Common patterns include coagulative necrosis, liquefactive necrosis, and caseous necrosis.

Necrosis is a pathological process and is generally indicative of disease or injury. It is a significant concern in medicine, as it can lead to organ damage and dysfunction. For example, necrosis of heart muscle cells occurs during a heart attack, and necrosis of brain cells can result from a stroke. Treatment for conditions involving necrosis often focuses on addressing the underlying cause and managing the inflammatory response.
