Human physiology

A.Y. 2020/2021
Overall hours
Learning objectives
The course aims at providing theoretical knowledge about the general organizational principles of the human body, including functioning at various levels, from the molecular and cellular to the various systems and the body as a whole; provide knowledge on the functioning of various organ systems and homeostatic mechanisms of the main regulated variables; to learn the relationship between physiological mechanisms and the state of nutrition.
Expected learning outcomes
At the end of the course the student will acquire the fundamental knowledge of human physiological functioning, in particular of the organ systems and the main homeostatic mechanisms. He/she will be able to understand how nutrition influences and is influenced by multiple homeostatic mechanisms and how physiological adaptation is at the basis of the state of nutrition. He/she will therefore be prepared to face nutritional evaluation, dietetics and pathophysiology of food-related diseases and human nutrition.
