Clinical Pathophysiology explores the physiological processes underlying human diseases, integrating foundational concepts in anatomy, physiology, and biochemistry to explain how disruptions at the molecular, cellular, and organ levels lead to clinical manifestations. Students examine major disease mechanisms including inflammation, infection, immune responses, hemodynamic disorders, and neoplasia while linking these mechanisms to specific conditions affecting various body systems. Through case studies and real-world examples, the course emphasizes diagnostic reasoning, clinical correlations, and the application of pathophysiological principles in medical decision-making and patient care.
