  1. The Epithelium TissuesGlandular epithelium Prepared by: Reem Aldossari

  2. Glandular Epithelium • a gland may consist of one cell or a group of cells highly specialized to secrete substances into ducts, onto surfaces, or into the blood. • Glands are classified as exocrine or endocrine • Unicellular Exocrine Glands • Goblet Cell • simplest form of exocrine gland; isolated secretory cell in an epithelium • goblet cells are found in the epithelial lining of the intestine and portions of the respiratory tract • goblet cells are goblet-shaped, thin at the basal side and expanded on the apical portion • apical portion of goblet cell is filled with large mucous producing secretory granules
