The Epithelium Tissues Glandular epithelium Prepared by: Reem Aldossari

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
