Learning Objectives

Human Physiology, AA 2017-2018
Knowledge and skills to acquire:

Knowledge of organism function, from basic molecular mechanisms to the function of cells and whole organs, as well as organ functional integration in complex beings. Full knowledge of all the subjects included in the program below. Ability to analyze and synthesize subjects, understanding mechanisms in details and subsequently summarizing functional finalities. Ability to expose subjects clearly and extensively. Understanding that a full knowledge of Physiology subjects is essential to exert a profession in pharmaceutical and medical fields.
General Pathology
At the end of the course the student will understand the underlying causes and pathogenetic mechanisms of human diseases, as well as the etiology of the fundamental alterations of the structures, functions and mechanisms of control. They will also know the basic biological mechanisms of defence and their alterations. The course will develop from the molecular level to higher grades of organization (cell, tissue, organ, apparatus, organism)
