The aim of Physiology I is to gain good knowledge about the functions of the human body in health. The subject Physiology I is taught in the form of lectures, practical classes and seminars. Emphasis is mainly focesed on functional organization, on the mechanisms controlling the internal environment of the organism, interrelationships among the control of individual functions and on the coordination and integration of functions.
Lectures: concept of homeostasis, body fluid compartments, blood and its functions (hemostasis, blood groups), introduction to immunology (innate and adaptive immunity), general neurophysiology (ion transport across the membrane, resting and action membrane potential, synapses), myology (skeletal and smooth muscle), central nervous system (spinal reflexes, regulation of posture and movement, reticular formation, autonomic nervous system, function of different parts of the CNS, CNS metabolism, wakefulness and sleep, lower and higher nervous activity, speech), cardiovascular system (cardiac muscle, conductive system of the heart, cardiac cycle, ECG, cardiac output and its regulation, blood flow, functional classification of the circulatory system, microcirculation, regulation of CVS activity) and respiratory system (ventilation, diffusion, transport of respiratory gases by blood, pulmonary circulation, regulation of breathing).
Practical classes: selected methods and examinations used in clinical practice (basic hematological examinations with an emphasis on hemocoagulation tests, blood group tests, WBC count, basic principles of neurological examination, ECG recording and evaluation, blood pressure measurement, cardiac stress tests).
Entry requirements: prerequisites: completed Anatomy II
Outcomes: 1. the student acquires basic theoretical knowledge about the function of the blood, the immune system, general neurophysiology and myology, the central nervous system and the cardiovascular system 2. the student acquires practical skills related to important clinical and laboratory examinations and learns to interpret the obtained results 3. the student gets to know the basic ways of obtaining scientific information 4. the student is capable of basic medical thinking based on model case studies.

To obtain credit for Physiology I, the following conditions must be fulfilled:
I. General – attendance and conduct code in the classes
Attendance at practical classes and seminars is mandatory and students are to be in their seats in time. Students come properly prepared for performing the planned practical class and knowing the theory immediately related to the class. The number of absences must not exceed 2 practical classes of all practical classes in winter term. Late coming irrespective of reason, a serious negligence of preparedness for practical class, or deliberately leaving class earlier will be considered and recorded as absence. If more than 2 practical classes per term are missed it is necessary to document the reason (e.g. a certificate of illness from a doctor) and the reexamination from all practical classes in semester is required. Unexcused absences for more than 2 practical classes and any absence (even excused) greater than 8 practical classes per semester will be dealt by the head of the Department of Physiology.
The organization of the practical classes may change in the light of the current epidemic situation and the regulations in force. Behaviour in practical classrooms and laboratories must follow the rules explained in the first class.
II. Protocols
Each student must record results and discussion of every performed practical task in Manuals for the Practical Classes in Physiology. The completed practical class protocols will be checked at the final (credit) practical class.
III. Knowledge
Each student must pass 4 tests in winter term (Physiology of Blood and Body Fluids, Immune System, General Neurophysiology and Myology, Central Nervous System). Each test is in the form of a multiple-choice questionnaire and consists of 20 questions, every question offers 4 answers (different variants of the correct answers). Points will be deducted for a wrong answer. Minimal scoring grade in each test is 60 %. It is strictly forbidden to use any electronic devices or to cheat in any other way during tests. If the student violates this rule, he will be graded "insufficient". If the student fails the test, he is entitled up to 2 retake tests. The dates of the tests and retake tests will be announced at the beginning of the winter semester. Tests are usually performed on tablets in the Moodle system. The organization of the tests may change in the light of the current epidemic situation.
