Epithelial tissues are of following types:
(1) Simple squamous epithelium
(2) Stratified squamous epithelium
(3) Columnar epithelium, and
(4) Cubodial epithelium.
These tissues differ in structure that correlate with their unique functions. For example, in cells lining blood vessels or lung alveoli, where transportation of substances occurs through a selectively permeable surface, there is a simple flat kind of epithelium. This is called the simple squamous epithelium. Simple squamous epithelial cells are extremely thin and flat and form a delicate lining. The skin. oesophagus and the lining of the mouth are also covered with squamous epithelium.
