Function: Relatively fast absorption and secretion Location: Some exocrine and endocrine glands, ducts

A single layer thin, flattened cells. Found in areas where diffusion or filtration occurs

Shape of the cells in epithelial tissues

Function: forming protective layer against force, friction, desiccation Location: areas exposed to repeated and prolonged exposure to force, friction, and air

Thick layer of cells: cuboidal cells on basement membrane, flattened, eosinophillic, anuckeate cells on apical surface

Means elongated

Funtion: Large amount of absorption, secretion, protection Location: lining and glands of majority of gastrointestinal tracts

Function: Lining, protecting areas of the body that meed more strength and resistance Location: Areast that require protection and strength

Number of layer of cells in epithelial tissue

Always has a free surface and basement membrane

Cells appear stratified but every cell contacts basement

Function: reducing number of layers and flattening the cells as the organ distends, then recoiling back to normal shape Location: lining of calyces, renal pelvis, ureter, urinary bladder, portions of urethra

Thick layer of cells: cuboidal cells on basement membrane: flattened but nucleated cells on apical surface

Lacks blodd vessels, so nourishment comes from the underlying connective tissue by diffusion movement

Number of layers and shape of the cells change based on distention of the organ

Two or more layers of cuboidal cells

Function: increasing surface area of the luminal border Location: areas that require large ampunt of absorption and secretion

Four general types of tissue

Function: absorption, secretion, generation pf current across the epithelium Location: most of respiratory tract

Function: Large amount of absorption and secretion Location: Lining of the intestine and respiratory tract

Many layers of flattened cells. Cells at the bottom layers are the youngest and cuboidal- shapped, and will become flattened as they move upward tp higher layers.

Function: Fast transport of molecules across cytoplasm, or protection in many layers Location: Areas that require rapid exchange of molecules or protection in many layers

Major tossue component of glands

Function: Relatively quick absorption, secretion Location: kidney tubules, pancreatic acini, small ducts, thyroid follicles

Function: Allowing distention and recp of an organ Location: Urinary bladder, ureter, calyces, urethra

Specialized to produce and secrete chemical substances into ducts or body fluids. Made pf cuboidal or columnar cells

Function: absorption, secretion, generation of current across the epithelium Locatipn: lining of fallopian tube

Secrete their products(hormones) directly into blood or body fluids ( all Hormonal glands are endocrine glands)

Single layer of ciliated columnar cells, pther types of cells intermixed

Means multiple layer

A single layer of cube-shaped cells. Found in areas where secretion or absorption occurs

Function: maintaining the shape and patency of duncts Location: interlobular and intralobular ducts

Means cube-shape

Use ducts to secrete their products into an open space ( sweat glands, oil glands, salivary glands, and tear glands)

Function and location: Lining absorption, secretion, creating curent across epithilium

Means flattened

Function: increasing surface area for absorption, serving as mechanoreceptors Location: epididymis, specialized sensory epithelium

Means single layer

Covering of body surfaces and internal organs, and lining, of body cavities

Function: protection from repeated, prolonged exposure to force and friction, preventing desiccation Location: skin

Single layer of columnar cells that appears to be multiple-layered because of its multiple-layered nuclei

Function: generating movements to create current Location: areas that require movement of fluids over the epithelium

A single layer of elongated cells. Designed for protection, secretion, or absorption

Function: Lining body cavities pr glands, absorption secretion Location: Areas that require quick transport of materials, large amount of absorption and secretion

Function: protection from repeated, prolonged exposure to force and friction Location: oral cavity, esophagus, vagina, anal canal

More than one layer of polygonal cells dome cells: rounded, sometimes binucleate cells protruding out into the lumen on apical surface

Simple squampus epithelium lining blood vessels and heart is called

Function: Rapid exchange of gas; small, lipid-soluble molecules; and fluid Location: luminal lining of vessels, lung alveoli, body cavity serous lining
