Epithelial Tissue

Tissue that covers a body surface of lines a body cavity, forms parts of most glands

To Protect, Absorb, Support, Filter, form Slippery Surfaces

Has no blood supply

Composed of mostly cells, very thin so oxygen and food can easily get to them, differing apical and basal cell regions, supported by an underlying connective tissue, avascular, and high capacity for regeneration

First name indicates number of cell layers, last name describes cell shape

One layer of cells

More than one layer of cells

Cells are wide, flat, plate-like

Cells are like cubes

Cells are tall, like columns

Single layer of flattened cells

To allow passage of materials

Found in lungs, kidney, blood vessels

Single layer of cube-like cells with large special central nuclei

Kidney and ducts of small glands

Single layer of tall cells with round to oval nuclei

To asbsorb and secrete substances and decide what needs to go in and what goes out

Stomach

Single layer of cells of differing heights, giving the false appearance of more than one layer, when it is actually a single layer

Offers protection from stuff you inhale

Found in the Trachea, windpipe

Two layers of cube-like cells

Protection

Found in Gland Ducts

Several cell layers, in an enlongated column shape

To Protect and Secrete

Rare, but sometimes found in small amounts in ducts of some glands and male uretha

to secrete and absorb

Resembles both stratified squamous and stratifed cuboidal.

To stretch, go from one shape to another without breaking

Found in the Bladder, Ureters

cells that make and secrete product

Ducts that carry products to the epithelial surface

Onto the body surface (skin) or into body cavities (digestive tube)

sweat glands, oil glands, mammary glands, salivary glands, pancreas, mucus

Ductless glands that secrete substances directly into the bloodstream

Glands that produce hormones in the body
