EPITHELIAL TISSUE (EPITHELIUM)
Epithelial tissue (Epithelium) Lining, covering and glandular tissue of
the body
Epithelial tissue (Epithelium) Examples:
Skin protects against bacteria/chemicals Lining of the respiratory tract-cilia to sweep
mucus Kidney-epithelium absorbs and filters Secretion-glands
Epithelial tissue (Epithelium)
Forms membranes for filtration/exchange
Glands/Ducts Salivary Glands Ducts in
Pancreas
Kidney tubules Surface of
ovaries
Line digestive tract
Goblet cells: produce mucus
Some cells are shorter than others
Absorption and secretion
Ciliated variety lines the respiratory tract
Goblet cells make mucus
Cilia move mucus
Pseudostratified (ciliated) columnar
Several layers of cells
Can stand friction: Esophagus Mouth skin
Cells at base are cuboidal or columnar, free surface varies
Tissue can stretch
Lines the: Urinary bladder Ureters Part of urethra
Extracellular matrix Produced by connective tissue cells Secreted to exterior
Ground substance, proteins and large polysaccharides
Matrix fibers
Gel like, to firm, to rock hard
