To be admitted to the final exam of Human Physiology 1 it is necessary to possess a positive evaluation of the exams of Human Anatomy

Final Examination: 

The evaluation of the attainment of the objectives foreseen by the integrated Course is performed through a final exam on all issues presented in the detailed program of the Courses of Human Physiology 1 and Human Physiology 2. The exam consists of a multiple choices test of 40 questions, whose positive evaluation (score higher than 18/30) allows to proceed to the oral evaluation, consisting of open questions. The whole exam aims at defining the knowledge and the degree of comprehensions of the human physiological mechanisms, the capacity to apply knowledge and comprehension and the learning capacity of the issues dealt with in the courses of Human Physiology 1 and Human Physiology 2.
The score of the exam of Human Physiology will take into account the evaluation of both the exams of Human Physiology 1 and Human Physiology 2.

Voto Finale

Physiology studies the human vital functions and analyses he 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.
The objective of the Course Human Physiology 1 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.

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
