Epithelial Tissues

Front 1

Simple Squamous - Function

Back 1

Function: Allows passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substance in serosae

Front 2

Simple Squamous - Location

Back 2

Kidney glomeruli, air sacs, lining of heart, blood vessels, lymphatic vessels, lining of ventral body cavity (serosae)

Front 3

Simple Cuboidal - Function

Back 3

Secretion and Absorption

Front 4

Simple Cuboidal - Location

Back 4

Kidney tubules, ducts and secretary portions of small glands, ovary surfaces

Front 5

Simple Columnar - Function

Back 5

Absorption, secretion of mucus/enzymes/other substances, ciliated type propels mucus by ciliary action

Front 6

Simple Columnar - Location

Back 6

Nonciliated type lines most of the digestive tract (stomach to anal canal), gallbladder, excretory ducts of some glands

Ciliated - lines small bronchi, uterine tube, some regions of the uterus

Front 7

Pseudostratified Ciliated Columnar - Function

Back 7

Secretion, particularly of mucus, propulsion of mucus by ciliary action

Front 8

Pseudostratified Ciliated Columnar - Location

Back 8

Nonciliated type in male's sperm-carrying ducts and ducts of large glands

Ciliated variety lines the trachea, most of the upper respiratory tract

Front 9

Stratified Squamous - Function

Back 9

Protects underlying tissues in areas subject to abrasion

Front 10

Stratified Squamous - Location

Back 10

Nonkeratinized type - forms moist linings of esophagus, mouth, vagina, urethra, anus

Keratinized type - epidermis of the skin, dry membrane

Front 11

Stratified Cuboidal - Function

Back 11

Protection

Front 12

Stratified Cuboidal - Location

Back 12

Largest ducts of sweat glands, mammary glands, and salivary glands

Front 13

Stratified Columnar - Function

Back 13

Protection and Secretion

Front 14

Stratified Columnar - Location

Back 14

Rare, small amounts in male urethra, large ducts of some glands

Front 15

Transitional Epithelium - Function

Back 15

Stretches readily and permits distension of urinary organ by contained urine

Front 16

Transitional Epithelium - Location

Back 16

Lines ureters, bladder, and part of urethra
