Seminars in Physiology 2

Data

Official data in SubjectManager for the following academic year: 2023-2024

Topic

The course is a consultation-type seminar related to the Physiology 2 course in groups of a maximum of 10 people. Six times during the semester, following the theme of the physiology lectures, we will help with the understanding and adequate preparation for the physiology final exams. During the lessons, following the needs of the students, we will discuss the problematic parts of the core material, and we will help the study of physiology with tests and problem-solving tasks. We recommend the course to dentistry, pharmacy, and general medicine students. The course starts in the 3rd week of the semester.
