Groups of closely associated cells that are similar in structure and perform a common function
The study of tissues
Tissue specialised for the covering and lining the body and organs, and glands
The surface of cell exposed to lumen or exterior
The cavity or channel within a tubular structure
Has no blood vessels
A nonliving adhesive material formed largely of glycoproteins secreted by the epithelial cells
Extracellular material containing fine collagenous or reticular fibres secreted by connective tissue cells abutting the basal lamina
The material formed by the basal and reticular laminae on which epithelial tissue is supported, defining the boundary of epithelial tissue.
Flattened and scalelike epithelial cells
Epithelial cells that are approximately as tall as they are wide
Epithelial cells that are tall and column-shaped
A single layer of epithelial cells
Multiple cell layers of epithelial cells
Tissues that look like they have more than one layer, but actually don't
Simple Squamous Epithelium
Single layer of thin cells found where filtration or exchange of substances by diffusion takes place
The simple squamous epithelium forming the serosae of the ventral body cavities
Simple Cuboidal Epithelium
Single layer of cuboidal cells found in kidney tubules, ducts of small glands and ovary surface
Simple Columnar Epithelium
Single layer of tall cells found lining most of the digestive tract; may be ciliated
Unicellular exocrine gland which secretes mucin; found in the digestive tract
Single layer of cells of DIFFERING HEIGHTS; found in the male urethra and upper respiratory tract; may be ciliated.
stratified squamous epithelium
Multiple layers of flat cells; found in the mouth, oesophagus and vagina
keratinised stratified squamous epithelium
Multiple layers of flat cells of which the top layers has dead cells filled with keratin; forms the skin
Superficial layer of the skin made up of keratinised stratified squamous epithelium
stratified cuboidal epithelium
Two layers of cube-like cells found in ducts of sweat glands, mammary glands and salivary glands
stratified columnar epithelium
Several layers with the top layer having tall cells; found in small amounts at epithelial junctions in the digestive tract and the conjunctiva.
Multiple layers of cells which appear cuboidal when not stretched, but squamous when stretched; found in the urinary organs
protection, absorption, filtration, secretion
Four functions of epithelial tissues
