The objective of the Course of Human Physiology is to provide to the Students all information needed to understand, from the biophysical and quantitative standpoint, the mechanisms of functioning of body organs and systems and their control performed by the central and autonomic nervous system and by the endocrine system.

The course will be presented through frontal lessons with slides. Students are encouraged to interact with teachers with questions and curiosities. During lectures, the lecturers will also present examples and daily facts that can make sense of the application / importance of the subjects of the lessons.
Students are required to attend the lessons as set out in the teaching regulations of the course and sign the attendance sheet to be able to take the exam.
