4.1 – Epithelial Tissue
Tissues
 ________________________ are made up of _____________________
o __________________ connect with one another via different
___________________________ to form
_______________________
 ______________________ junctions: _______________

join together _________________
________________________
 Example: cells in the intestine
 ______________ junctions: _____________________ or
“gaps” between cells that allow the ___________________
of molecules
 Example: calcium moving between cells
 ________________________ junctions: act like
“_________________________” to hold the cells
_________________________________ in the tissue
 Example: skin cells
There are 4 ________________________ tissue types
1. ______________________________: covers the __________________ ________________________,
lines body cavities and forms _________________________
2. ______________________________: _______________________ and __________________________
the body
3. ______________________________: generates physical _______________________ needed for
________________ _________________________
4. ______________________________: detects _________________________ inside and
______________________ the body, ______________________________ body activities
Epithelial Tissue
 Divided into 2 types
1. ________________________ &_____________________ epithelium:
 Covers the _____________________ ______________________ of the body and
__________________ internal organs
2. _______________________________ epithelium:
 Makes up the _______________________ portion of _____________________ (sweat glands)
 _______________________ hormones or other products


Functions
o ___________________________, absorption, __________________________ and secretion
Characteristics
1. Epithelial cells are packed __________________________ _____________________ to form
______________________________ ___________________
2. Epithelial cells have an ______________________ surface and a _____________________ surface
 _____________________: most ________________________________ layer of cells
 _____________________: _______________________ layer of cells; between the
___________________________ and the underlying ______________________________ tissue
3. Epithelial cells are ____________________________; they lack __________________ _______________
4. Can _________________________ easily—cells are ____________________________
____________________
Covering and Lining Epithelium
o Classified according to the _______________________ of
_____________________ and the _____________________ of the
____________________
o
o
Number of Layers:
 _______________________: _____________ layer

_______________________: more than _______________ layer

_____________________________________: looks like
_________________ layers but it’s only ________________ layer
Shape of cells
 __________________________: _________________________

__________________________: ___________________ - ___________________

__________________________: _________________________-_____________
o
_________________________ Epithelium
1. __________________________ _____________________________
 _____________________ layer of __________________
cells
 Found in the _________ ____________ of
________________ and _________________ of the
__________________ and blood vessels
 Allow material to pass through by
______________________ and ____________________
 ___________________________ lubricating substances
2. ____________________________ _____________________________
 ___________________ layer of flat ________________-shaped cells
 Found in the ________________ and ________________________ portions of small
____________________ and in kidney tubules
 ________________________ and _____________________
3. __________________________
__________________________
 ______________________ layer of
tall/______________________ like cells
 Ciliated Tissues: found in
_____________________, uterine tubes and the
_____________________
 Smooth(unciliated tissues): found in the ________________________ tract,
_________________________
 _________________________ and
______________________ mucous and
_______________________
4. _________________________________________
 _____________________ layer of cells, some
are _______________________ than other
 Often looks like a ___________________________ layer
 Lines the _________________________ and the upper ___________________________
tract
 _________________________ mucus, and moves mucus
o
___________________________ Epithelium
1. ____________________________ ___________________________
 ______________________ layers of _________________ ________________________
 Lines the ___________________________, ______________________ and vagina
 ________________________ against ________________________
2. _______________________________ cuboidal
 Rare
 Function is mainly ___________________________, secretion and
_________________________
3. Stratified ______________________________
 ________________________
 Function is protection and secretion
4. _______________________________ Epithelium
 _________________________ of cells depends upon the amount of
_________________________________
 Lines the ____________________________, urethra and the _____________________
 Allows the __________________________ organs to ________________________ and
_____________________________

_________________________________ Epithelium
o Function is to __________________________ ______________________, hormones, ______________,
______________________, earwax, saliva and mucus
o Two Major glandular epithelium gland types
 __________________________ gland: secretes _____________________________
____________________ into the ______________________________________
 Example: thyroid gland secretes the hormone thyroxin into the bloodstream
and is distributed throughout the body raising metabolism
 _________________________
gland:
secretes
their
substances
into
_________________
which carry the secretions to the ___________________________ surface
 Example: sweat glands, saliva and mammary glands
