Blood vascular organization of the walls of vermiform appendix from human fetus. Examination of vascular corrosion casts in SEM.

Ten human vermiform appendices obtained from fetal corpses (160.0-240.0 mm of CRL) were examined using injection-micro corrosion method. Blood vascular bed reproduced with this method was observed with scanning electron microscope (SEM). Blood vascular bed structure of foetal appendix has been described, simultaneously with produced by them plexuses and organisation of microcirculation in a wall of the appendix. Collected results have been compared with data of other authors who conducted similar research on adult human appendices and appendices of several animal species.
