PPT-Glandular Epithelium

Made of cells that secrete substances into ducts or body fluids Almost always columnar and cuboidal epithelia Exocrine vs Endocrine Exocrine Glands secrete their products into ducts that open onto surfaces ex skin lining of digestive tract. 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.
