Q- Tabulate the structural peculiarities, location and function of squamous epithelium, ciliated columnar epithelium and stratified epithelium.
Answer- Squamous Epithelium:
The cells in squamous epithelium are flat, thin, dicoidal and polygonal in shape which fit like the tile in the floor. The nuclei in these cells are flat and oval in shape.
The squamous epithelium are located or found in the alveoli of lung, mouth, oesophagus and coelum.
Squamous epithelium performs several functions in different parts but the main function of squamous epithelium is that it is responsible for exchange of gases of gases top help in the process of respiration.
Ciliated columnar epithelium:
Ciliated columnar epithelium consists of cells which are columnar in structure they are arranged in column form.
The Ciliated columnar epithelium is found in the respiratory tract where mucous and air is pushes away to clear the respiratory tract. And some other areas such as: fallopian tubes, uterus, and central canal of spinal cord e.t.c.
Ciliated columnar epithelium performs several functions in different parts but the main function of ciliated columnar epithelium is that it helps in movement of mucus and other substances via cilia and is found in the upper respiratory duct.
Stratified epithelium is consisted of two more types of cells layer. It is a part of epithelial tissue that works for providing cover to the inner organs.
The Stratified epithelium are found or located in urethra, ducts of many gland, mouth, mammary gland.
Stratified epithelium performs several functions in different parts but the main function of stratified epithelium is that it provides cover or layer to other inner organs or parts of the body.
