We studied 120 capsules from 90 cadavers, both male and female, aged 0-18 years who died from causes unrelated to the liver. When conducting the research, we instilled a water soluble agent of black ink at a 1:3 ratio through the abdominal artery of the cadavers aged 0-3 years, then peeled off the capsule and placed the catheter in the liver artery by the method described by V.P.Vorobiev (1925), D.Amgalanbaatar (1984), and B.Dagdanbazar (1992). We then prepared a slide and microscopically studied the microcirculation of arteries I, II ,and III of the liver capsule. With larger children’s cadavers, we disected the liver, placed a catheter into the artery, and instilled the solution. We took micro photos from slide preparations and examined the pattern of the blood vessel branching of the liver capsules of our Mongolian cadaver subjects to determine the general regularity of the microcirculation and the order of blood vessel branching.

We learned from our study that the microcirculation of the liver capsule originates from the dexter and sinister branches of the superior and inferior phrenic arteries, dexter and sinister suprarenal artery, and dexter and sinister branches of the internal thoracic artery. When the diameter of the branching arteries in order I, II, and III of the capsule are decreased in diameter, they form double, triple, and tetra branches having a rectangular shape. Veins follow these arteries in a combined single or double form. Two venules are formed following one arteriole through the microcirculation of the liver capsule that become a module with a multi-angle circle. In its center arteriole, precapillary, capillary, and postcapillary vessels form the blood’s in-and-outflow network.
