Study Notes
Cellular Injury and Adaptation
- Irreversible cell injury can be caused by ischemia, which is a reduction in blood flow leading to reduced oxygen delivery to cells.
- Reversible cell injury occurs when cells are exposed to hypoxia, infectious agents, or toxins, leading to impaired cellular function but not cell death.
- Extreme temperatures are an example of a physical agent that can cause cellular injury.
- Hyperplasia is a type of adaptation that involves an increase in cell number, often in response to chronic injury or inflammation.
- Pesticides are an example of a chemical agent that can cause cellular injury by disrupting cellular function or inducing cell death.
