one, looks like many
Simple squamous Advantages, functions, and features
very thin, excellent at allowing gasses and molecules to pass by diffusion
simple squamous location
Lungs and blood vessels
Simple cuboidal advantages, functions, and features
good at secretion of substances and absorption of substances
Simple cuboidal location
Glands and kidneys
Simple columnar advantages, function, features
Good at absorption of substances and secretion of mucus
simple columnar location
lines the intestines
Stratified squamous advantages, functions, and features
made of many layers of cells, found in locations that undergo abrasion and need protection
stratified squamous location
Outer layer of skin, mouth, esophagus, vagina
Stratified Cuboidal advantages, functions, features
extremely rare
Stratified cuboidal location
In the ducts of large glands such as mammary glands or sweat glands
stratified columnar advantages
rare
stratified columnar location
pharynx and male urethra
pseudostratified columnar advantages, functions, features
Good at secretion of substances such as mucus have cilia that can push small particles through the organ
Transitional
usually stratified bottom cells are columnar or cuboidal; top cells transition from dome like to squamous can stretch easily
transitional location
hollow urinary organs such as bladder, uterus, and part of urethra
