Bacteria e adipocyte fat cells that store

bacteria.
e. Adipocyte: fat cells that store triglycerides.
f. leukocytes (white blood cell): gather at sites of infection when not in the
bloodstream, other types migrate to the sites of parasitic invasions and
allergic responses.
III. connective tissue extracellular matrix: unique to certain types of connective
tissue
IV. ground substance: the component of a connective tissue between cells and
fibers. It supports cells, binds them together, stores water and provides a
medium for exchanging substances between blood and cells.
V. Fibers: embedded in the extracellular matrix between cells
a. collagen fiber: very strong and resist pulling forces, but are not stiff,
allow flexibility
b. elastic fiber; elasticity: branch and join together to form a fibrous
network. Contain the protein elastin, surrounded by fibrillin, which add
elasticity and strength. Can stretch up to 150% of their relaxed length
and still return to original shape, a property called elasticity.
c. reticular fiber; stroma: consist of collagen arranged in fine bundles with
a coating of glycoprotein, provide support in the walls of blood vessels,
sometimes form a network around cells in some tissues. Plentiful in
reticular connective tissue, which forms the stroma: supporting
framework of many soft organs.
7. Describe the structure, function and location of each of the types of connective tissue listed
below.
8. mature connective tissues: brief descriptions, locations and functions

supply this tissue.
Reticular Connective Tissue:
Fine interlacing network of
reticular fibers, (thin form of
collagen fiber) and reticular
cells.
Stroma of liver, spleen, lymph
nodes, red bone marrow,
reticular lamina of basement
membrane and around blood
vessels and muscles.
Forms stroma of organs, binds
smooth muscle tissue cells,
filters and removes worn-out
blood cells in spleen and
microbes in lymph nodes.
B. dense connective tissue: contains more fibers which are thicker and more densely
packed, but have many less cells than loose connective tissue.
Dense Regular: forms shine
white extracellular matrix,
