The presence of lymphatic stomata in the ovarian bursa on the European beaver as shown by scanning electron microscopy study

Abstract

The internal and external epithelial sheets of the ovarian bursa in the European Beaver were examined using scanning electron microscopy. Two types of epithelial cells were found on both surfaces, but only in the areas of the cuboid cells were the lymphatic stomata created This suggests that the absorption and passage of fluid, particles and cells between the peritoneal and ovarian bursa cavities and lymphatic lumen in the beaver are possible.
