Epithelial Tissue

epithelial tissue

makes up coverings

endocrine glands

secrete into blood

shapes of epithelial cells

squamous, cuboidal, columnar

exocrine glands

secrete onto a surface

squamous

flat and thin

cuboidal

square shaped

columnar

rectangular shaped

simple

one layer

stratified

more than one layer

pseudostratified

one layer but looks like more than one

4 types of tissue

epithelial, connective, nervous, muscle

type of tissue without blood supply

epithelial tissue

apical surface

free surface (not attached)

basal surface

attached to basement membrane

avascular

lacks blood

epithelial tissue characteristics

cover surfaces, lines organs and cavities, has a free surface, avascular, reproduces rapidly, packed tightly together

epithelial functions

protetion, absorption, excretion, produce secretions

glandular epithelium

typically columnar shaped

apical surface

basement membrane

noncellular and nonliving structure that anchors to epithelial tissue

Simple squamous epithelium shape

One layer of thin, flat cells

Simple squamous epithelium location

Alveoli of lungs; lining of blood vessels and heart; serous membranes

Simple cuboidal epithelium shape

One layer of cube shaped cells with round central nuclei

Simple cuboidal epithelium location

Kidney tubules; ducts and secretory portions of many glands

Simple columnar epithelium shape

One layer of tall, rectangular cells; oval nuclei usually near the base

Simple columnar epithelium location

Stomach and intestines; much of the digestive tract

Pseudostratified columnar epithelium shape

One layer of tall cells that looks multilayers because nuclei sit at different heights; often ciliated

Pseudostratified columnar epithelium locatioon

Much of the respiratory tract, including the trachea

Stratified squamous epithelium shape

Many layers; cells at the surface are flat

Stratified squamous epithelium location

Mouth, esophagus, and vagina

Stratified cuboidal epithelium shape

Multiple layers; surface cells are cube shaped

Stratified cuboidal epithelium location

Sweat duct glands

Stratified columnar epithelium shape

Multiple layers; surface cells are tall/column shaped

Stratified columnar epithelium location

Parts of the male urethra and some large ducts

Transitional epithelium shape

Multiple layers; surface cells are rounded/dome shaped and flatten when stretched

Transitional epithelium location

Urinary bladder and ureters
