educational material for the anatomy practicals and anatomy exam. The first chapter provides introduction to the cardiovascular system, the heart and basic description of the circulations. The second chapter deals with the organs of respiratory system. The text is fulfilled by the photographs of formalin fixed cadaveric preparates used during the anatomy practicals in our department, however, it is necessary combine the study with using of anatomy atlases (Sobotta´s, Gray´s, Gilroy ´s or Netter´s atlas of human anatomy).
