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 and respiratory systems and the stomatognathic apparatus.

Teaching methods
The course will be held through lectures to Students either in the classroom (“in presenza”) or in synchronous-streaming (“in telepresenza”) on the Teams platform. Therefore, the opportunity of Student/Teacher interaction will be preserved both face to face and remotely, by the simultaneous use of the Teams platform.
Lectures will be supported by slide presentations, which will be available to students on the Elly platform (https://elly2020.medicina.unipr.it/).
Assessment methods and criteria
Oral examination.
In case of the persistence of the health emergency, the exams will be conducted remotely, as follows:
remote oral questions, through the Teams platform (guide http://selma.unipr.it/).
Students with SLD / BSE must first contact Le Eli-che: support for students with disabilities, D.S.A., B.E.S. (https://sea.unipr.it/it/servizi/le-eli-che-supporto-studenti-con-disabilita-dsa-bes)
