Course abstract

Physiology is the fundamental science of Biology. It studies the principles of physiological processes of the organism – vital functions of the cells, organs and systems, their relationships and mechanisms of regulation.
Knowledge of physiology is needed to understand complicated physiological processes of the body and their mechanisms of regulation, to understand causes of functional processes occurring in the body under the influence of various factors of the external and internal environment.
In the first part of the course students learn history of physiology and basic concepts (homeostasis, defence mechanisms, etc.), physiology of excitable tissues – muscles, nerves, CNS and glands, physiology of the blood and circulatory system

Learning outcomes and their assessment

Knowledge – about history of physiology, body’s homeostasis and the ways how the body maintains it, excitable tissues and their action, blood composition and functions, the functioning of the blood circulatory system, and the main regulatory mechanisms. Assessment – 4 tests.
Skills –to evaluate different physiological processes in the excitable tissues, organs of the circulatory system and the body as a whole, the interactions and results of these processes. Control – practical works.
Competence –to apply acquired knowledge about the blood composition and the determination of physiological parameters related to blood circulation and the evaluation of their fluctuations within the limits of physiological norms for different animal species, to be able to apply the acquired knowledge in subsequent clinical subject studies. Control – defence of practical work protocols at the end of the semester.

Course Content(Calendar)

1. Introduction to physiology - history, homeostasis, body defense systems, basic mechanisms of regulation of functions - 6 h lectures and 9 h practical works.
1st test. Introduction to physiology.
2. Physiology of excitable tissues: muscle tissue, nervous system and CNS - 8 h lectures and 12 h practical works. Homework on regulation of adenohypophyses-dependent glandular activity.
2nd test - Physiology of excitable tissues.
3. Glandular: endocrine and exocrine glands physiology - 8 h lectures and 12 h practical works. Homework about the role of vitamins, micro-and microelements in the body's processes. Independent work - Gland research methods - historically and nowadays.
3rd test - Physiology of the glands.
4. Physiology of the blood and blood circulatory system - 10 h lectures and 15 h practical works.
4th test–Physiology of blood and blood circulatory system.

Requirements for awarding credit points

The study course ends with assesment “passed”. To achieve it, four tests (according to the generally accepted 10 point system) must be succesfully completed, two homeworks and one independent work must be defended, at least 70% od the total number of classes must be attended and laboraotry works must be defended.
If unfulifilled absance of course is more than 30% of the total number of lessons, then the course must be re-mastered.
If the attendence of the lessons is sufficient, but the student has not gained the evaulation “passed’ until the end of the indivdual studies and examinations (session) due to other reasons, the debts can be taken during the next semester (i.e., until the session!), the time and form should be arranged with the academic staff. If any of the requirements is not fullfilled in time, the entire study course Physilogy I must be repeated.

Description of the organization and tasks of students’ independent work

During the semester at practical works, the student receives two individual homework/tasks, which should be defended in the next practical work, or, in agreement with the lecturer, at another time, receiving a successful assessment (according to the general

Criteria for Evaluating Learning Outcomes

Upon completion of each subject, the student’s knowledge is evaluated based on the results of the test written in the practical works. Student’s skills are assessed in accordance with the procedures specified in the practical assignments The student’s competence is assessed by individually defended two homework and one independent work. By competing the course Physiology I, during the final week of the semester students defend the protocols of practical works, demonstrating their knowledge, skills and competence.
