[Systematization of the angioarchitectonics of the colon in adult man].
The systematization of the angioarchitecture of the human colon was studied in 25 colons, the vascular system of which was injected with gelatinous indian ink. The arterial vascularization of the colonic wall is organized in two morphologically very different types of networks. The first type forms the distributional networks which consist of the subserosal, intermuscular and submucosal networks distributing harmoniously the blood running from the straight arteries. The second type forms the functional networks which consist of the muscular and mucosal networks related to the supply of the essential structure of the colonic wall. These consist essentially of pre- and postcapillary vessels. The venous vascularization of the colonic wall is organized according to a similar pattern. It also consists of three venous networks: the submucosal, intermuscular and subserosal networks which are tributaries of the straight veins and which receive the mucosal and muscular veins.
