rather yellowish- white appearance, are the pyloric glands (Fig. 112, A) found, in 

 general in smaller number. At their lower extremity their ducts are not rarely 

 divided into two or more blind sacs. Their cellular contents consist, as a rule,

 c, reticular connective tissue. II. Sect-ion through the Glands of the Fundus: a, chief cells; h, parietal

 chief cells (h h) and parietal cells (b b); the 

 latter exhibit intracellular secretory canals. 

 Between the chief cells intercellular secretory 

 ducts (z z) penetrate for some distance; a,
