To be admitted to the final exam of Human Physiology it is necessary to possess a positive evaluation of the exam of Human Anatomy
The evaluation of the attainment of the objectives foreseen by the integrated Course of Physiopatology will be performed through two separate tests of Human Physiology and of Pathology. The exam of Physiology consists of a multiple choices test of 40 questions delivered through a PC with a score of 0.825 for each correct answer and 0 for each wrong or missing answer.
The exam of Pathology will be performed through a test with written open questions. The exam aims at defining the knowledge and the degree of comprehensions of the human physiological and pathological mechanisms, the capacity to apply knowledge and comprehension and the learning capacity of the issues dealt with in the two aggregated Courses.
The exam is passed for scores higher than 18/30.
Pathophysiology studies the human vital functions in normal and altered conditions and analyses the mechanisms through which the organism realizes ad maintains its internal homeostasis at molecular, cellular and tissue level in spite of the modification of the surrounding environment. In addition it describes the mechanisms through which drugs modify the cellular and tussue functions.
The objective of the Course of Pathophysiology will be to provide graduates with all the information necessary to understand, from a biophysical-quantitative point of view, the functioning of the various organs and systems of the body under normal conditions and their control by the nervous system central and autonomous and endocrine system.
Dublin descriptor 1: knowledge and understanding
Students must learn the basics of biophysics and the functioning of cells, tissues and organs in physiological conditions;
Dublin descriptor 2: applied knowledge and understanding
Students must use the acquired knowledge to understand complex and integrated physiological mechanisms.
Dublin descriptor 3: independent judgment
Ability to reason about the correlation between structure, biophysical behavior and the function of organs and systems.
Dublin descriptor 4: communication skills
Capability to clearly describe the discussed issues by using the adequate technical language.
Dublin descriptor 5: ability to learn
Ability to associate quantitative and functional parameters with changes in physiological conditions.
The Course will deal with the physiology and pathology of the following systems:
Central and autonomous nervous system.
Skeletal muscle and locomotion.
Vascular systemic circulation and lymphatic system.
Pulmonary and coronary circulation. Control of cardiovascular function.
Respiratory system, gas exchanges and transport.
Nervous and chemical control of respiratory function.
Renal system and regulation of volume and osmoticity in extracellular body fluids.

For the Physiology course:
AA.VV. – FISIOLOGIA DELL'UOMO - a cura di P.E Di Prampero e A. Veicsteinas - Casa Editrice Edi-Ermes, Milano
AA.VV. – FISIOLOGIA – a cura di P.Scotto, P. Mondola - Poletto Editore, Milano
Teaching will be given through frontal lessons. With the aid of images, schemas, graphs and biophysical analysis of the functioning mechanisms of cells, tissues and organs, the student will be driven to the comprehension of the different but integrated physiological processes
Professors are available for the students through appointment set through the their institutional e-mail address.
