2. EPITHELIAL TISSUE
(COVERING)
Tightlyjoined closelypacked cells
One side of exposed to air or
internal fluid, other side attached to
a basement membrane
Covers outside of the body and lines
internal organs and cavities
Barrier against mechanical injury,
invasive microorganisms, and fluid
loss
Provides surface for absorption,
excretion and transport of molecules
