Objectives

To acquire to the student the basic knowledge of the laws of chemistry and of the properties of the main inorganic and organic compounds of biological interest; know and understand the relationship between structure and function of macromolecules of biological-medical relevance; know the most important human biochemical processes and their regulation.
To acquire: the knowledge of the physiological mechanisms of the vital processes at the cellular level, of excitable tissues and of the different organs and systems of the human body and the understanding of the functioning of the different organs and systems and of the general mechanisms of homeostatic control under normal conditions and adaptation

Evaluation methods

Verification of learning:

The exam method is a written test designed to verify the results of the expected learning, in accordance with the educational and specific objectives of the course. The examination is placed at the end of the course, after having achieved the attendance to the same, according to a schedule established and published on the personal page of the student at the beginning of the academic year, which provides (2) two appeals for canonical session exam. The outcome of the test is evaluated as the result of learning the specific and training objectives, such as knowledge and understanding, capacity for logical integration
and application. At the end of the test each teacher will form an opinion expressed in bands of vote and thirty:A) excellent knowledge and understanding of the subjects, ability to reason and logical integration of the acquired knowledge and insertion in the context of an application in the pathophysiology. Rating: 30/30. If the student, who has achieved this evaluation, demonstrates autonomy of judgment, high communication skills and autonomous learning skills, praise will be proposed. B) Good knowledge and understanding of the topics with some non-serious inaccuracies and with a good capacity for logical integration and judgment, and application in the pathophysiology rating: 27-29 / 30 C) Discrete knowledge and understanding of the topics and, despite some gaps in the ability to integrate and apply knowledge. Rating: 24-26 / 30 D) Knowledge and understanding of the arguments fully sufficient, although there are clear gaps, which are reflected in a reduced capacity for integration, logic and application. Rating 21-23 / 30 E) Knowledge and understanding of the topics with serious and evident gaps, with limited integrative and applicative skills, but which also allow the passing of the exam. Rating 18-20 / 30
