Epithelial Tissue Flashcards
what is epithelial tissue
- covers body surfaces in and out
- attached to connective tissue at
basement membrane - reproduce rapidly, rapid healing (scarring)
Functions of epithelial tissue
protection, secretion, absorbtion, excretion, senses
Single layer-
simple
multiple layers
stratified
flat
squamous
square
cuboidal
rectangle/column
columnar
Form of simple squamous
flat, thin, single layer
Function of simple squamous
Diffusion of oxygen and CO2
location of simple squamous
air sacs of lungs, capillaries
Form of simple cuboidal
single layer, cube-shaped cells
Function of simple cuboidal
secretion and absorbtion
Location of simple cuboidal
kidney and ovaries
Form of Simple columnar
single layer, long cells
Function of simple columnar
absorbtion of nutrients
location of simple columnar
digestive tract
Form of stratified squamous
multi-layered, squamous cells
location of stratified squamous
outer layer of skin
function of stratified squamous
protection
pseudostratified columnar form
single layer with nucli at different levels
pseudostratified columnar function
moves air and removes debris
pseudostratified columnar location
air passages (trachea)
transitional epithelium form
thick layered cuboidal cells
transitional epithelium function
forms thin membrane
Transitional epithelium location
urinary bladder
Glandular epithelium function
secrete substances
function of cilia
movement
function of microvilli
increase absorption of nutrients
