The primary and secondary ducts arelined with simple columnar epithelium, the cells of which becomelower in the small ducts, till where these arise in the alveolithey are reduced to narrow, flattened, spindle-shaped cells (Fig. 25).The number of ducts in the pancreas is not constant even ina series of the same animals. In man they are usually two, theprincipal, or duct of Wirsung, and the accessory, or duct ofSantorini. The latter may be absent (Hess), in any case it isalways very minute in the adult, while in the early stages ofdevelopment it is larg
