The Epithelium Tissues

Glandular epithelium

Prepared by: Reem Aldossari

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 endocrineUnicellular Exocrine GlandsGoblet 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
