Epithelial Tissue

Give description, body location, and function

Simple Squamous: Description

Single layer of flattened cells, disc-shaped nuclei

Simple Columnar: Description

Single layer of rectangular cells; oval-shaped + basal nuclei

Simple Cuboidal: Description

Single layer of cube-like cells; round + central nuclei

Stratified Squamous: Description

Multiple layers of squamous cells; can be keratinized or nonkeratinized

Pseudostratified Columnar: Description

Single layer of columnar cells at different heights that give the appearance of stratification; may contain cilia

Transitional: Description

Multiple layers of cells that appear to transition to another type of tissue type; usually have a dome-shaped apical cell layer

Simple Squamous: Body Location

Air sacs of lungs, kidneys, lines heart, blood vessels, body cavity

Simple Columnar: Body Location

Digestive tract, uterine tube, gallbladder, kidney tubules

Simple Cuboidal: Body Location

Kidney tubules, lower respiratory passages, thyroid, salivary, and mammary glands

Stratified Squamous: Body Location

Epidermis of skin (keratinized) | Anal canal, vagina (nonkeratinized)

Pseudostratified Columnar: Body Location

Nasal cavity, male urethra, upper respiratory passages

Transitional: Body Location

Urinary bladder, ureters, urethra

Simple Squamous: Function

Diffusion, filtration, and secretes serous fluids

Simple Cuboidal: Function

Absorption and secretion of mucus + other substances

Simple Columnar: Function

Absorption and secretion of mucus + other substances; propels egg through uterine tube

Stratified Squamous: Function

Protection from mechanical stresses and microorganisms

Pseudostratified Columnar: Function

Secretes mucus with help from cilia

Transtitional: Function

Protections and gives tissue distensibility
