Pathophysiology is the study of the functional and physiological changes in the body that result from disease processes, injury, or abnormal syndromes. This course explores the underlying mechanisms that disrupt normal biological function, examining how alterations at the cellular, tissue, and organ levels manifest as clinical symptoms. Students will gain a foundational understanding of disease progression, including topics such as inflammation, immune responses, genetic disorders, and system-specific pathologies. Emphasis is placed on the application of pathophysiological principles to clinical practice, enabling students to connect basic science with patient care and medical decision-making.
