Learning objectives
The aim of this course is the study of the functions of body systems. Goal of the course is also to make the student aware of the functional relationship between various organ systems of the body as well as to explain the concept of internal environment and its regulation by homeostatic mechanisms. Understanding normal function and mechanisms of the human body will allow the student to understand, in future courses with a more clinical focus, the pathology and malfunctions of the human organs.
Expected learning outcomes
At the end of the course the student should understand the function of human physiological systems and should also understand how these separate systems interact to yield integrated physiological responses to challenges as fasting or exercise. This knowledge will be the base to understand topics explained in future courses focusses on pathology and pharmacology and clinical medicine.

Prerequisites for admission
For this course will be necessary a good knowledge of Human Anatomy and a basic knoledge of Biochemistry and Cell Biology
Teaching methods
This course is based on lectures. During the lectures many slides will be shown and explained and discussed.
Teaching Resources
1) Sherwood: Fondamenti di Fisiologia Umana- Piccin
2) Stanfield: Fisiologia - EDISES
3) Berne&Levy: Fisiologia - CEA
4) Silverthorn: Fisiologia Umana - Pearson
5) Zocchi: Principi di Fisiologia - EDISES
Assessment methods and Criteria
There are not ongoing tests during the course. There will be just a final exam, and this will be only oral, a discussion of about 15-45 min focussed primarely on the explanation of mechanisms of function of the human organs and organ systems. Will be also evaluated the knowledge of technical (medical) termes and the proper utilization in the discussions of those terms. There will be 6 possibilities to try the exam during the academic year, 2 in February, 2 in June-July and 2 in sept-oct.
