Conoscenze e abilità da conseguire

Understand the importance of the integration of physiological processes from the molecular level to complex systems. Describe the general principles of gastrointestinal function, including motility, nervous control, and blood circulation. Describe the mechanisms of gastrointestinal secretion, digestion and absorption. Summarize the principles of metabolism and temperature regulation. Summarize the endocrine and nervous regulation of food intake and energy storage.


Functional anatomy of gastrointestinal system
Structure of the gastrointestinal tract wall. Splanchnic circulation. Innervation of gastrointestinal system.

Neurohumoral regulation of the functions of the gastrointestinal system.

Nervous regulation of functions of gastrointestinal system: enteric nervous system, sympathetic and parasympathetic innervation, reflex activity. Hormonal regulation of gastrointestinal functions.

Motility of gastrointestinal system
Chewing. Swallowing. Motility of esophagus. Gastric motility: filling of stomach, movements of mixing and emptying of gastric contents. Vomiting. Emptying of gallbladder. Motility of small intestine, of large intestine and of rectum. Defecation.

Secretion of gastrointestinal system

Regulation of food intake
Nervous centers controlling food intake. Factors controlling the amount of food. Short and long-term regulation.

Energy Metabolism
Basal metabolic rate. Energy metabolism and its regulation systems. Direct calorimetry. Indirect calorimetry. Factors that influence energy metabolism. Functions of thyroid hormones, of glucocorticoids, of pancreatic hormones. Growth hormone.

Guyton & Hall, Textbook of Medical Physiology; 13rd ed.; Elsevier

Boron, Walter, Boulpaep, Emile: Medical Physiology, 3ed; Elsevier

You can find these books also in the Biblioteca Biomedica, via Filippo Re (Bologna).

All relevant teaching material will be available on the designated digital platforms (servers) of the University (IOL platform).


Metodi didattici

Frontal lessons using Power Point presentations.

Attendance to learning activities is mandatory; the minimum attendance requirement to be admitted to the final exam is 60% of lessons. For Integrated Courses (IC), the 60% attendance requirement refers to the total amount of I.C. lessons. Students who fail to meet the minimum attendance requirement will not be admitted to the final exam of the course, and will have to attend relevant classes again during the next academic year.

Professors may authorise excused absences upon receipt of proper justifying documentation, in case of illness or serious reasons. Excused absences do not count against a student’s attendance record to determine their minimum attendance requirement.

Modalità di verifica e valutazione dell'apprendimento

The final examination consists of an oral test in which the student will discuss mainly two different topics taken from the program. As part of the interview, questions will also be asked to evaluate the depth of the knowledge on the two topics and on other topics of the program, the critical thinking ability that links together different aspects of knowledge and the achievement of a comprehensive understanding of the topics addressed in class.

The exam will be considered passed if the student has demonstrated sufficient knowledge in each topic.

The student’s ability to move across the various topics of the Physiology program will be also evaluated. The student’s achievement of a comprehensive view of the topics addressed in class, together with their critical thought, the ability to make associations, the demonstration of rich and intelligible expression and use of specialist’s language will be evaluated with scores of excellence.

Strumenti a supporto della didattica

Lectures will be done in a Power Point presentation format. The material for the slides (e.g. figures, photos) will come mainly from the suggested textbooks. All relevant teaching material will be available on the designated digital platforms (servers) of the University (IOL platform).

In order to prepare for the exam it is suggested to attend actively the lectures, study from a textbook and use both the notes taken during lectures and the IOL material.
