What is pseudostratified?
it is only one layer but looks like it is several layers
what is the function of simple epithelium tissue?
to absorb and filtrate
what is the function of stratified epithelium ?
to protect
found in the blood vessels, lymphatic vessels, heart, and kidneys
simple squamous
found in the digestive tracts, ducts, and respiratory tract
simple columnar
found in kidney tubules and lining of ducts
simple columnar
pseudostratified is found in the
epididymis (tube that carries sperm) and upper respiratory tract
found in the vagina, oral cavity, and esophagus
stratified squamous
found in some sweat glands
stratified cubodial
found in the urinary tract (ureters, urinary bladder, urethra)
stratified epithelial
found in the ducts of large glands
stratified columnar
Epithelial tissue is classified as…
- number of cells
- shape of cells
- location
Epithelial glands are named based on their….
-secretion
-number of cells
- and structure
which tissue type has polarity and is avascular?
Epithelium
which tissue type consists of a sheet of cells that covers a body surface or lines a body cavity?
epithelial tissue
Function of epithelium tissue: secretion
simple cuboidal
Function of epithelium tissue: absorption
simple columnar epithelium with microvilli
Function of epithelium tissue: filtration
simple squamous
Function of epithelium tissue: protection
stratified squamous
lining this lumen, the cells seem to have long, fingerlike projections
simple columnar
