Learning outcomes

At the end of the course the student: - has clear the concepts of disease etiology and pathogenesis. He/she also knows the etiology of disease processes and the pathogenic mechanism of their development. He/she knows the basic defense mechanisms involved in response to pathogens; the morphological alterations that they cause in cells and tissues and their systemic and functional consequences for the organism. He/she- is able to connect molecular, morphological, microbiological, immunological and physiological knowledge, with the etiopathogenesis of disease processes. He/she is able to use the knowledge of pathology and physiopathology for the critical interpretation of experimental and clinical data. He/she is able to understand the reasons of the signs and symptoms of disease and possesses the basis for the evidence based clinical practice.

Teaching methods

A total of 64 hour of lectures.

Assessment methods

The exam is oral and consists of a part of Histopathology with recognition and discussion of histological preparations and discussions on parts of the program covered in the lectures. The final grade is determined by averaging the marks obtained in individual applications.

Teaching tools

Slides are available from the AMS Campus website.
