Study Notes
Pathology
- Study of the nature, causes, and effects of diseases.
- Examines structural and functional changes in tissues and organs resulting from disease processes.
Primary Cause of Cell Injury
- Hypoxia is the primary cause of cell injury, which results from inadequate oxygen supply to tissues.
Factors Affecting Cell Injury
- Various factors can influence the extent and nature of cell injury, including:
- Duration of injury exposure
- Severity of the insult
- Type of tissue affected
Physical (Exogenous) Agents of Cell Injury
- Physical agents include mechanical trauma, extreme temperatures, and radiation.
- Examples:
- Physical trauma can directly disrupt cell structure.
- Extreme temperatures can denature proteins and damage membranes.
Causes of Immunologic Diseases
- Immunologic diseases are primarily caused by:
- Abnormal immune responses, such as autoimmunity.
- Allergic reactions where the immune system reacts against harmless substances.
