02359 - General Pathology and Physiopathology (AK-A)

Learning outcomes

The students will learn the etiology of the disease processes, the pathogenetic mechanism of their development, the basic reactions to abnormal stimuli and the morphological changes they induce in cells and tissues, together with the systemic and functional consequences for the organism. By the elaboration of molecular, morphologic, microbiologic and immunologic knowledges, the students will understand the wherefores of the signs and symptoms manifested by patients and will be provided with a sound foundation for evidence based medicine.

Course contents

Each line of text (excluding titles) corresponds approximately to one hour teaching unit

Teaching methods

The course includes 64 hours of lessons on environmental, cellular and extracellular pathology, inflammatory-reparative response and general pathophysiology.

Assessment methods

The learning level will be assessed at the end of classes. The examination will include two questions to ascertain the knowledge the student has about the program subjects and his/her ability to discuss the etiopathogenesis and general pathophysiology of each subject. One of the two questions will include a practical microscopy test to assess the learning of the General Pathology Laboratory. The on line registration to the exam is mandatory.

Teaching tools

Slides containing schemes and figures will be projected during lessons. This educational material is available online at https://iol.unibo.it/
