Connective tissueghhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

1. Connective Tissue

2. Connective Tissue
Function:
-Binds structures together
-Provides support & protection
-Fills spaces
-Produces blood cells
-Stores fat
For energy, insulation, organ protection

3. Parts of tissues
Structure:
-Tissue cells are widely separated by
extracellular matrix
-Can be solid, semisolid, or liquid
Matrixof connective tissue determine its
properties

4. Fibers of the Matrix
White fibers–contain collagenwhich
gives the fibers flexibility and strength
Yellow fibers–contain elastinmore elastic
than collagen but not as strong
Reticular fibers–thin, highly branched
collagenous fibersthat provide support

19. Dense Regular
Dense Irregular

30. Adipose tissueis a
type of loose
connective tissue
-stores fats,
provides insulation
-found beneath
skin, around kidney
& heart, breast

31. B. Dense Connective Tissue
Regular
Consists of parallel
bundles of
collagenous fibers
Found in tendons &
ligaments
Binds organs together
Irregular
Bundles run in
different direction
Found in inner portion
of skin

32. 2. Cartilage
The cell
(chondrocytes)
lies in small
chambers called
lacunae
Matrix is solidyet
flexible
Lacks direct
blood supply, as
a result, it heals
slowly

33. 3 types
-Hyaline cartilage-trachea
-Elastic cartilage –ear
-Fibrocartilage -ACL

34. 3. Bones
Most rigidof the connective tissues
Minerals and protein fibers gives bone
rigidity, elasticity and strength
Two types:
Compact bone
Spongy bone

35. A. Compact Bone
Found in the outer portion of long bones
Consists of many cylindrical-shaped units
called osteon

37. B. Spongy Bone
Found on ends of long bone
Contains bony bars and plates called
trabeculaeseparated by irregular
spaces
Blood cells are made within the red
marrow found in the spongy bone

39. 4. Blood
Connective tissue
composed of cells
suspended in liquid matrix
called plasma
Red blood cells
(erythrocytes) –carries
oxygen
White blood cells
(leukocytes) –fights
infection
Platelets–fragment of
giant cells found in bone
marrow
