Study Notes
Cellular Injury
- Fatty change (steatosis) is defined as the accumulation of triglycerides in cells, typically in the liver.
- Irreversible cell death is caused by necrosis, a type of cell injury.
- The main cause of hypoxia-induced cell injury is a lack of oxygen, leading to cellular damage and potentially death.
- Edema, or the accumulation of excess fluid in tissues, contributes to reversible cell injury.
- The ability of cells to adjust their functions in response to different environmental stress is called adaptation.
