Learning objectives

The knowledge of the functional mechanisms of the human organs and apparati addressed during the course, the knowledge of their dynamic integration and the general mechanisms of functional control in normal conditions and in particular pathological conditions.

Prerequisites

Students must possess basic and fundamental notions of Anatomy, cell and tissue biology and biochemistry of the organs and systems which are the topic of this part of the course.

Course unit content

The course addresses the physiology of the human body, by focusing on the general processes, the cardiovascular, respiratory and nervous systems and the stomatognathic apparatus.
