epithelium location
body coverings, body linings, galndular tissue
epithelium funcitons
protect, absorb, filter, serete
characteristics of epithelium
cells fit closley together, always has 1 free surface, lower surface is bound by a basement membrance, avascular, regenerate easily
simple
one layer
stratified
more than 1 layer
psuedo stratified
one layer but looks like multiple
squamous
flat cells
cuboidal
cube shaped
columnar
column shaped
simple squamous epithelium
single layer of flat cells
locaiton of simple squamous epithelium
alveoli, cappillaries, forms serious membrane, covers organs in ventral cavity
apical surface
free, top surface of epithelium
basement membrane
bottom surface of epithelium
alveoli
sacks in lungs
capillaries
site of gas diffusion where veins and arteries meet
simple cuboidal epithelium
single layer of cube shaped cells
location of simple cubiodal epithelium
glands, ducts, salivary glads, pancreas, walls of kidney tubules, cover surface of ovaries
apical surface of simple cuboidal epithelium
inside of gland/duct
basement layer of simple cuboidal epithelium
outside of gland/duct
simple columnar epithelium
single layer of column shaped cells
location of simple columnar epithelium
lines body cavities (mucose), lines digestive tract
function of simple columnar epithelium
movement
cilia
aid in movement
simple columnar epithelium contains what cells
goblet cells
goblet cells
produce lubricating mucus (helps with movement in digestive tract)
pseudostratified columnar epithelium
looks like more than one layer but it’s a single layer of column-shaped cells
psuedostrafied columnar epithelium function
secrete and absorb
psuedostrafied columnar epithelium location
line respiratory tract
psuedostrafied columnar epithelium goblet cells
sticky trap, catch dust and debris in respiratory tract
psuedostrafied columnar epithelium cilia
aid in movement and propel mucus away from lungs
stratified squamous epithelium
multiple layers of flat cells (turn into cuboidal cells)
stratified squamous epithelium location
high friction and abuse: mouth, skin surface, esophagus, vagina
Most common epithelium
stratified squamous epithelium
stratified squamous epithelium nonkeratinized
moist lingings: esophagus, mouth, vagina
stratified squamous epithelium keratinized
hardened lingings: skin epidermis
stratified cuboidal epithelium
two layers of cube shaped cells
stratified cuboidal epithelium function
protection
stratified cuboidal epithelium location
largest ducts of sweat glands, mamary glands, and salivary glands
transitional epithelium
many layers of different shaped cells
transitional epithelium function
stretches and permits destension of urinary organ
transitional epithelium location
lines ureters, bladder, and parts of hte urethra
most abundant and widely distributed tissue
connective tissue
connective tissue function
bind body tissue together, support body, protect, cushion, insulate
