The course is focused on physical processes associated with blood flow and blood gas exchange, including description of events on biological membranes. Further, the possibilities of measuring advanced hemodynamic parameters of the bloodstream are discussed. A large space is devoted to the problems of hemodialysis and peritoneal dialysis. In the second part of the semester students are acquainted with the properties of human tissue and body fluids, including methods of their measurement. This knowledge is complemented by the basics of optics and acoustics, always in relation to biological systems. Part of the course are laboratory exercises in a modern laboratory, which suitably complement the theoretical knowledge of students from lectures.

Study targets:

Understanding physical laws concerning physiological processes in the human body and their application in solving practical biophysical problems.


In the first part of the semester, attention is paid to the cardiovascular system, followed by respiration, ie lung gas exchange and dialysis methods (hemodialysis, peritoneal dialysis). In the next part of the course the attention is paid to thermal radiation and body temperature measurement and also to the use of ionizing radiation in medicine. The last part of the semester is devoted to medical acoustics. Several excursions to specialized workplaces are planned during the semester.
