Assessment
Unaided Work:
During the course the students do individual and pair work – development of laboratory work according to the course themes; they study the given resources and scientific publications. Tasks about the blood flow, the structure of syringes, blood transfusion, calculation of the human body frame parameters.
Assessment Criteria:
Students participation in practical classes, individual assignment in the seminar and results of the practical work during the colloquium are evaluated. There are different types of test questions in the exam.
Final Examination (Full-Time):		Exam
