write the structure,function and location of any three types of epithelial tissues.

Dear student,

Simple squamous epithelium

• Simple squamous epithelium is a single layer of thin and flat cells.

• The cells are very thin with a delicate lining.

• Some examples of simple squamous epithelium are the lining of the mouth, oesophagus, lung alveoli and small blood vessels.

• The skin is also composed of simple squamous epithelium. Epithelial cells in the skin are arranged in many layers to prevent wear and tear. This type of multilayered epithelium is known asstratified squamous epithelium.

  Cuboidal epithelium

  • Cuboidal epithelium consists of cube-like cells.

  • These tissues are present in the lining of kidney tubules and ducts of salivary glands.

  • Some special cuboidal cells form the surface of secretory glands and gland cells.

    Columnar epithelium

    • Columnar epithelium consists of elongated or column-like cells.

    • These tissues are mainly found in the parts where absorption and secretion occur.

    • Some examples of columnar epithelium are the inner linings of the intestine and gut.
