Back 1

thin, flat, irregular cells, each with one central nucleus

Front 2

Simple squamous epithelium (function)

Back 2

Diffusion; osmosis; filtration

Front 3

Simple squamous epithelium (location)

Back 3

Lungs and kidneys

Front 4

Simple cuboidal epithelium (comp)

Back 4

squarish cells, each with a spherical central nucleus

Front 5

Simple cuboidal epithelium (function)

Back 5

Absorption; secretion

Front 6

Simple cuboidal epithelium (location)

Back 6

Kidney tubules and lining of ducts of salivary glands

Front 7

Simple columnar epithelium (comp)

Back 7

elongated rectangular cells, each with a single nucleus located near the base of the cell

Front 8

Simple columnar epithelium (function)

Back 8

Secretion; absorption

Front 9

Simple columnar epithelium (location)

Back 9

Non-ciliated columnar epithelium in small intestine contains goblet cells that secrete mucus and microvilli that increase surface area to enhance absorption

Ciliated columnar epithelium in uterine tubes moves oocytes toward uterus

Front 10

Pseudostratified columnar epithelium (comp)

Back 10

cells of different heights that rest on same basement membrane, but the nuclei are located at different levels so the tissue appears to have multiple layers

Front 11

Pseudostratified columnar epithelium (function)

Back 11

Secretes mucus; moves mucus by ciliary action

Front 12

Pseudostratified columnar epithelium (location)

Back 12

Lines most of upper respiratory tract and portions of male reproductive tract

Front 13

Stratified squamous epithelium (comp)

Back 13

multiple layers of cells and is most widespread epithelium in body

Front 14

Stratified squamous epithelium (function)

Back 14

Protects against pathogens; resists abrasion; retards water loss

Front 15

Stratified squamous epithelium (location)

Back 15

Keratinized epithelium on skin surface contains layer of dead squamous cells filled with waterproof keratin protein

Non-keratinized epithelium covers tongue; lines mouth, esophagus, anal canal, vagina; because it lacks a surface layer of dead squamous cells it is moist and slippery

Front 16

Stratified cuboidal epithelium (comp)

Back 16

two or more layers of cube-shaped cells

Front 17

Stratified cuboidal epithelium (function)

Back 17

Protection; limited secretion; absorption

Front 18

Stratified cuboidal epithelium (location)

Back 18

Ducts of sweat glands and Ovaries and testes

Front 19

Stratified columnar epithelium (location)

Back 19

quite rare and found only in limited regions of the pharynx, larynx, anal canal, and male urethra.

Front 20

Transitional epithelium (comp)

Back 20

rounded or cuboidal cells that become squamous cells as the tissue stretches

Front 21

Transitional epithelium (function)

Back 21

Permits distension of an organ or structure

Front 22

Transitional epithelium (location)

Back 22

Located in ureters, urinary bladder, part of urethra

Front 23

Areolar loose connective tissue (comp)

Back 23

collagen fibers, elastic fibers, and reticular fibers and cells that are embedded in a semi-fluid ground substance

Front 24

Areolar loose connective tissue (function)

Back 24

Binds epithelium to tissue; provides strength and support

Front 25

Areolar loose connective tissue (location)

Back 25

o Thin, delicate membranes located beneath skin
o Located between skin and muscles

Front 32

Dense regular connective tissue (comp)

Back 32

parallel bundles of collagen fibers

Front 33

Dense regular connective tissue (function)

Back 33

Its orderly arrangement provides strength

Front 34

Dense regular connective tissue (location)

Back 34
