It serves as the sheath organ from the animal kingdom in the preparation of the dandelion flower heads. The peritoneum (*Serosa*, *Peritoneum*) sheathes the abdominal cavity and all the organs contained within it, as well as the pelvic cavity. In the abdominal and pelvic cavity it forms the boundary membrane of the metabolic pole in the proper sense. The thoracic cavity too — the centre of the rhythmic system with heart and lungs — is lined by a *Peritoneum*, the pleura. This, however, is strictly separated from the peritoneum by the diaphragm (*Diaphragma*). The *Peritoneum* is a skin organ turned inward, inverted into the inner world of the body. Its surface, facing inward, is formed by squamous cells embedded in a basement membrane. This membrane rests upon the connective and muscle tissue of the walls of the organ sheaths and body cavities respectively. If one detaches it, one holds in one's hands a translucent, lustrous, membrane-like skin. It is traversed by a fine network of nerve fibres that centre themselves in individual ganglia and finally converge in the great ganglion centre of the solar plexus (*Plexus solare*), which in the ox lies beneath the spine at the boundary region
