PPT-Glandular Specialized Epithelium

Glandular Specialized Epithelium Specialized Epithelial Tissue are a class of epithelial tissues that have very specific and specialized functions and structures This tissue is composed of cuboidal columnar ciliated columnar epithelial cells. Epithelial tissue is found lining internal surfaces and covering external surfaces of the body Thus it is classified in general terms as covering and lining epithelium Epithelial functions include protecting the body from the environment transportin Glandular fever Glandular fever (infective mononucleosis) is a viral infection commonly occurring in young people.
