Epithelial tissue class 9th

Epithelial tissue




EPITHELIAL TISSUES
  • It consists of cells which form membranes.
  • This membrane covers the body surface and the glands.
  • The covering or protective tissues in the animal body are epithelial tissues.
  • Epithelium covers most organs and cavities within the body.
  • It also forms a barrier to keep different body systems separate.
  • The skin, the lining of the mouth, the lining of blood vessels, lung alveoli and kidney tubules are all made of epithelial tissue.
  • The cells are tightly packed and form a continuous sheet.
  • They have only a small amount of cementing material between them and almost no intercellular spaces.
  • These are divided into four types:-


SIMPLE
  • The cells are extremely thin and flat and form a delicate lining.
  • The lining of oesophagus and the mouth are covered with squamous epithelium.
STRATIFIED
  • The cells are arranged in many layers to prevent wear and tear.
  • Since they are arranged in a pattern of layers, the epithelium is called stratified squamous
  • The skin, which protects the body, is made of squamous epithelium.
COLUMNAR
  • The columnar (meaning ‘pillar-like’) epithelium facilitates movement across the epithelial barrier.
  • It is present where absorption and secretion occur, as in the inner lining of the intestine, tall epithelial cells are present.
  • In the respiratory tract, the columnar epithelial tissue also has cilia, which are hair-like projections on the outer surfaces of epithelial cells.
  • These cilia can move, and their movement pushes the mucus forward to clear it. This type of epithelium is thus ciliated columnar epithelium.
CUBOIDAL
  • Cuboidal epithelium (with cube-shaped cells) forms the lining of kidney tubules and ducts of salivary glands, where it provides mechanical support.
  • Epithelial cells often acquire additional specialisation as gland cells, which can secrete substances at the epithelial surface.
  • Sometimes a portion of the epithelial tissue folds inward and a multicellular gland is formed.
  • This is glandular epithelium.
  • Sometimes epithelial tissue takes special function of secretion the it is called glandukar epithelial 
  • Tissue e.g. sweat gland oil gland etc.l
  • Quiz time
  • Name the following 
  • Epithelial tissue present in 
  • Cheek inner lining---------
  • Blood vessels lining ----------
  • Small intestine-----------
  • Trachea-------
  • Sweat gland--------
  • Skin----------
  • Help box-------Glandular epithelial tissue ,Ciliated columnar epithelial tissue ,
  • Columnar Epithelial tissue ,Squamous ET ,Stratified Squamous ET,cuboidal ET


Name the following
