|
loose connective tissue
|
fill spaces between organs, cushion and support
|
|
|
3 kinds of loose connective tissues
|
1. areolar
2. adipose 3. reticular |
|
|
areolar
|
open framework, made mostly of ground substance, forms a layer hat separates skin from deeper structures
|
|
|
adipose
|
made of mainly apipocytes, absorb shock, insulator, lipid breakdown releases energy as heat, adipocytes deflate when nutrients are scare but still remain, do not divide in adults but can be produced by mesenchymal cells
|
|
|
reticular
|
support parenchyma of spleen/liver
|
|
|
dense connective tissue
|
mostly collagen fibers
|
|
|
2 kinds of dense connective tissue
|
regular
irregular |
|
|
dense regular
|
collagen is paraellel and densely packed
i.e. tendons and ligaments |
|
|
dense irregular
|
no consistent pattern of the collagen
i.e. skin |
|
|
fluid connective tissue
|
blood and lymph
|
|
|
3 things plasma contains
|
RBC
WBC platelets |
|
|
RBC
|
carries oxygen/CO2
|
|
|
WBC
|
immune response
|
|
|
platelets
|
for clotting
|
|
|
lymphs contains
|
lymphocytes
|
|
|
4 tissues of the body
|
1. Epithelial
2. Connective 3. Muscle 4. Neural |
|
|
epithelium
|
includes epithelia (cells that line) and glands
|
|
|
5 characteristics of the epithelium
|
1. cellularity
2. avascularity 3. polarity 4. attachment 5. regeneration |
|
|
cellularity
|
bound by junctions
|
|
|
avascularity
|
obtain nutrients through diffusion and absoption
|
|
|
polarity
|
the difference between cells from the inside and out
|
|
|
attachment
|
some attach by a basal lamina
|
|
|
regeneration
|
replaced by stem cell division
|
|
|
4 functions of the epithelium
|
1. protection
2. control premeability 3. provide sensation 4. production secretion |
|
|
3 specialization
|
1. movement of fluid for control premeability
2. and protection 3. produce secretion |
