Transcript Tissues - MyCAERT


Tissues are groups
of cells similar in
structure and
function
Epithelial Tissue, Connective Tissue,



Epithelial tissue is
composed almost
entirely of cells.
It is supported by
connective tissue ,
reticular, and basal
laminae.
It is Avasular but
innervated, contains
no blood vessels but
supported by nerve
fibers
Tissue, Simple Epithelial, Stratified
Epithelial, Transitional Epithelial


Simple Epithelia are
single layered cells
It is usually located
in places where
there is lots of
absorption and
filtration.
Tissue, Epithelial Tissue,
Simple Squamous, Cuboidal,
Columnar


In Simple Squamous
the cells appear to
be flattened.
Also found where
filtration occurs, for
example in the
kidneys or lungs.
Tissue, Simple Epithelial


Simple Cuboidal
has a nucleus in the
shape of a sphere
and is a single layer
of cells.
It is important
because it secretes
and absorbs.
Tissue, Simple Epithelial



Single layer of tall
cells that are tightly
packed in together.
Absorbs and secretes
and is used in the
lining of the
digestive tract in the
stomach.
Lined with cilia to
move substances
through the
passageways.
Tissue, Simple Epithelial Tissue



These cells often
vary in height.
Because the heights
vary, it gives off
fake (pseudo)
looking layers.
Secretes and
absorbs along the
lungs.
Tissues, Simple Epithelial


Major role in these
cells are protection
Two or more cells
that divide and
regenerate, to
replace the older
more worn surface
of cells
Tissue, Epithelial, Simple
Squamous, Cuboidal, Columnar



Stratifies Squamous
has many different
layers.
Usually found in
places that are
more likely to tear
It is used for
protection
Tissue, Stratified Epithelial


Very rare in the
human body
They are sometimes
found in ducts and
in larger glands
such as sweat
glands and
mammary glands.
Tissue, Stratified Epithelial


Can be found in the
lining of glandular
ducts, pharynx, and
the male urethra.
Occurs as
transitional areas
between other
types of epithelia
Tissues, Stratified Epithelial



Its basal layer is
cuboidal and
columnar.
It is found in the
urinary organs and
stretches as urine is
produced.
When urine is
present it stretches
from six layers to
about three.
Tissue, Epithelial Tissue


This type of tissue
is very common in
the body.
There are many
different forms of
connective tissue
and it does way
more than just
connect
body parts.
Tissues,
Connective Tissue Proper
Cartilage,
Blood, Bone, Connective
Tissue Proper Loose,
Dense


Connective tissue is
located all among
the body.
It is used to
connect muscle to
muscle, bone to
bone, and muscle
to bone.
Tissue, Connective Tissue,
Hyaline Cartilage, Elastic
Cartilage, Fibrocartilage



Hyaline Cartilage is
the most abundant
in the body.
Provides firm
support
It covers long ends
on bones and
provides
compression on
joints.
Tissue, Connective Tissue
Proper



Very similar to
Hyaline Cartilage.
There are more
elastic fibers
It has a great
amount of strength
and flexibility
Tissue, Connective Tissue Proper



It is similar to
hyaline cartilage,
and dense regular
connective tissues.
It is compressible
and has tension
resistency
Located where
heavy amounts of
pressure are
required.
Tissue, Connective Tissue,
Fibrocartilage


Surrounded my a
nonliving fluid called
blood plasma.
Blood carries out
functions such as
carrying nutrients,
wastes, respiratory
gases and other
substances
throughout our
bodies.
Tissue, Connective Tissue



A connective tissue
that forms the
Skeleton
Hard and calcifies
matrix with
collagen fibers
found in bone.
Supports, protects,
and provides levers
for muscular action.
Tissue, Connective Tissue



Classified as an
areolar connective
tissue
Is gel like and
wraps around as
well as cushions
organs.
It is widely
distributed
thoroughout the
body.
Tissue, Connective Tissue,
Loose Adipose, Reticular
Reserves food
stores, insulates
against heat loss,
and supports and
protects.
 Found under skin,
around kindeys,
within the
abdomen, and in
breasts.
Tissue, Loose Connective

Tissue


Forms a soft
internal skeleton
that support other
cell types.
Found in lymph
nodes, bone
marrow, and in the
spleen.
Tissue, Loose Connective
Tissue



Fibroblasts are the
major cell type.
Found in tendons ,
ligaments, and
aponeuroses.
Attaches muscle to
muscle, muscle to
bone, and bone to
bone.
Tissue, Connective, Dense
Regular, Dense Irregular

Has parallel
collagen and cell
type is fibroblasts
Tissue, Dense Connective Tissue



Can withstand
tension in many
directions
Irregularly arranged
collagen fibers
Major cell type is
fibroblasts
Tissues, Dense Connective
Tissue


Fast acting control
system
It triggers muscle
contraction as well
as gland secretion.
Tissues



Highly cellular
Responsible for
most body
movements
Highly vascularized
Tissue, Skeletal , Cardiac,
Smooth


Attached by the
bones of the
skeleton.
This muscle forms
skin and flesh, and
is responsible for
bodily movements.
Tissue, Muscle Tissue



Only found on the
wall of the heart.
When is contracts it
helps flow blood to
the heart.
Cardiac cell
muscles are
striated.
Tissue, Muscle Tissue



Called Smooth
muscle because its
cells have to visible
striations.
Spindle shaped and
contain a nucleus in
the center.
It acts to squeeze
substances through
organs by
contracting and
relaxing.
