Study Notes
Cellular Injury and its Consequences
- Cellular injury often leads to cell death, impacting tissue function and overall organ health.
- Necrosis is a common outcome, characterized by uncontrolled cell death resulting from factors such as lack of blood flow or toxic exposure.
Causes of Cellular Injury
- Typical causes include hypoxia, chemical exposure, infections, and physical trauma.
- Factors that are not typical causes may include genetic variability and lifestyle choices, though these can indirectly contribute to overall cellular health.
Effects of Oxidative Stress
- Oxidative stress results from an imbalance between free radicals and antioxidants in the body.
- This stress can damage cellular components such as proteins, lipids, and DNA, leading to impaired cell function and increased risk of diseases.
Necrosis Process
- Necrosis involves rapid cell death due to injury, characterized by cell swelling, rupture, and inflammation.
- This process often triggers an immune response, leading to further tissue damage and possible complications.
Consequences of Chronic Cellular Injury
- Chronic cellular injury can result in cellular adaptations such as hyperplasia (increased cell numbers) or hypertrophy (increased cell size).
- Long-term effects may include fibrosis, organ dysfunction, and increased susceptibility to diseases such as cancer or cardiovascular conditions.
