[The morphological characteristics of the cecum and its lymphoid tissue in BALB/C mice].

The caecum has been studied at the light optic and electron microscopical levels. Amount of immune-competent cells and lymphoid nodules in the distal part of the mice caecum and in the human appendix vermiformis are essentially similar. It is possible to consider the distal (blindly closed) part of the caecum in the mice of the BALB/C line as a morphofunctional equivalent to the human appendix vermiformis and use it as an experimental model in studying diseases of the appendix.
