gap junctions
hemidesosomes
Tight junction:
prevents leakage
Desmosome:
has strong proteins strands in between plaques

folds
There is ____ layer in microvilli
one
What does microvilli do to the surface absorption
increase the area
Where are microvilli mainly found
intestines
Microvilli fold in the walls of the intestine and …
fold within the epithelial cells themselves
Cilia can act to work like a
brush border
Cilia acts to
keep stuff off tissues
Where are cilia mainly found
respiratory tract
Cilia has cells to _______ to catch impurities
secrete mucous
