Arterial system of the head and anterior portion of the trunk of Balaenoptera edeni

As demonstrates the investigation of the blood system in the whale (Balaenoptera edeni) performed by means of the macropreparation of corrosive casts and sawcuts, in this species, as in other Cetacea, there is a well developed complex of the arterial rete mirabile, owing to which the brain is supplied with blood. In the whale mentioned this complex is comparable with that in dolphins and is noticeably less developed than in the spermacet (Physeter sp.). Angioarchitectonic of the whale has much in common with the arterial system of representatives of Balaenopteridae family, previously studied.
