The studies were carried out on 100 right lungs and 100 left lungs taken from cadavers of humans of both sexes, aged 18 to 80 years. After swilling, the bronchi were injected with 65% duracryl and after 24 hours digested in sulphuric acid. The obtained casts were measured and the modes of division of superior lobar bronchi were determined. The results of observation and measurements were presented in the form of schematic drawings and documented with photographs. On the basis of the modes of branching of superior lobar bronchi three types and eight variants of division for the right lobar bronchus and two types and five variants for the left lobar bronchus were identified. The divergence between the frequency of some modes of division of the studied bronchi, especially according to authors from other countries and very similar results of investigations relating to atypical modes of division of some bronchi, performed in Poland and neighbouring countries, were noted.
