Topographo-anatomical features of the distribution of outflow tracts of blood from major structures of venous pericardial bloodstream have been determined during the research, conducted on hearts, received at autopsies of male and female cadavers of 21–75 ages. Venous pericardial bloodstream is represented by venous vessels, longitudinal venous vessels, longitudinal venous tracts, single-layer and bi-layer venous network as well as venous paravasal veniplexes.
