01
a type of cell death that occurs due to injury, infection, inflammation, or other forms of cellular stress
What is "necrosis"?
Necrosis is the early death of cells and tissues in the body, often resulting from factors such as infection, toxins, trauma, or lack of blood supply. This type of cell death typically leads to inflammation and can cause the affected tissue to break down. There are different types of necrosis, and managing it often involves removing the dead tissue and treating the underlying cause to prevent further damage and infection.
Example
Traumatic injury, such as a car accident or a gunshot wound, can cause necrosis in the affected tissue.
The autopsy revealed that the cause of death was necrosis of the liver due to acute alcohol poisoning.
Gangrene is a type of necrosis that occurs when there is a lack of blood supply to the affected area.
The doctor diagnosed necrosis in the patient's limbs, which had turned black and blue due to lack of blood flow.
In contrast to necrosis, necrobiosis is a programmed process that occurs in response to specific signals, rather than as a result of injury or stress.
