Presentation transcript:

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

Extracellular matrix

Types of Connective Tissue  Bone  Cartilage  Dense Connective Tissue  Loose Connective Tissue  Blood
