Learning Objectives
5 objectives- Understand the basic principles and mechanisms of pathophysiology and how disease processes affect normal body functions.
- Analyze cellular adaptations, injury mechanisms, and the body’s inflammatory and immune responses.
- Explore the pathophysiology of major organ systems including cardiovascular, respiratory, neurological, endocrine, renal, and gastrointestinal systems.
- Identify common genetic disorders and inherited diseases and understand their pathophysiological basis.
- Apply knowledge of pathophysiological processes to clinical scenarios and disease management.
