Learning objectives
The knowledge of the functional mechanisms of the human organs and apparati taugh 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
The knowledge of the functional mechanisms of the human organs and apparati taught during the course, the knowledge of their dynamic integration and the general mechanisms of functional control in normal conditions and in particular pathological conditions.
Course unit content
The course addresses the second part of the physiology of the human body, by focusing on the physiology of the heart and circulatory system and of the respiratory and urinary systems.
Full programme
