6 credits during the 1st year of 11158 APPLIED AND EXPERIMENTAL BIOLOGY (LM-6) GENOVA
2° Semester
Teaching materials


The course explores the study of the mechanisms of regulation of metabolic homeostasis in humans, addressing the regulation of the various functions by the nervous system and the endocrine system and highlighting the existing integrations between the various systems. The course explores human nutrition physiology and the importance of proper nutrition for maintaining health, during the different phases of human life and in various physiological states.



The course aims to provide in-depth knowledge on human physiology and particularly on the importance of proper nutrition for maintaining homeostasis, highlighting and enhancing the relationships of connection and interdependence between physiological processes and mechanisms.


Participation in the course will allow students to deepen the knowledge of Physiology learned during the Bachelor's Degree, with specific reference to humans and nutritional needs. This knowledge is necessary for the career opportunities of the biologist, particularly in health and alimentary fields.

The course aims to provide a complete vision of Human Physiology and allows the student to acquire detailed information on how the different organs of the human body work, on the dynamic integration of the organs in systems, on the general mechanisms of homeostatic control under normal conditions and adaptation, with a specific attention to the nutritional and metabolic needs during life course e in different physiological states. The role of food as a signal integrated in the human regulatory network will be highlighted.

 At the end of the course the student must be able to:

• know how the human organism work at the molecular, cellular, organ and system levels.

• Acquire an integrated view of the physiological mechanisms that regulate homeostasis and adaptation processes in humans.

• know how the human organism works as a whole.

• Understanding simple pathophysiological situations resulting from the loss of homeostatic regulation.

• Highlight the link between structure and function at the level of organs and systems.

• Acquire a correct terminology in the pathophysiological field.

  • Know food requirements.

• Know how the organism digests, absorbs and uses macronutrients.

• Know the importance of micronutrients.

• Acquire an integrated view of the processes that regulate human nutrition.

• Understand the importance of proper nutrition and a healthy lifestyle for maintaining health.

• Acquire a critical view of the many food "fads" that are often spread by the mass media.


Basic knowledge of biochemistry, physiology, genetics and pathology is required to effectively address the teaching content.

Exam description

The exam consists of an oral interview of about thirty minutes, conducted by a commission consisting of at least two members, during which the student will have to explain some of the topics covered in class. At least 2 calls will be available in the winter session (January-February) and 5 calls in the summer session (June, July, September).

Please refer to AulaWeb for any updates due to changes in the health and epidemiological situation.

Assessment methods

The Commission verifies the achievement of the educational objectives by asking different questions related to the program actually carried out during the lessons. Details on the degree of in-depth knowledge for each topic will be provided during the lessons.

The oral examination allows to evaluate the knowledge of the fundamental elements of the subject and the ability to link the various topics. During the interview the Commission will verify if the student has acquired the ability to apply the theoretical concepts to simple concrete contexts. The quality of the speech and the use of the correct specialized scientific terminology will also be evaluated. When the training objectives are not achieved, the student is invited to better verify his / her knowledge and possibly to make use of further explanations by contacting the teacher in charge of the course.
