lots of valves preventing
Lymphatic vessels backflow
Approx 3 liters of fluid perday is forced under
pressure out of BV
When fluid exits BV washes around tissues
it is called interstitial fluid Fluid must be
returned to blood system it's the lymphatic
system that accomplishes this Interstitial
fluid enters lymph vessels where name changes to
lymph fluid then cleaned up returned to bloodsystem
, Removal of Interstitial fluid from tissues spaces begins at
blind ended lymphatic capillaries that are found weaving btwn loose
connective tissue cells of body
Lymphatic capillaries are widespread in body but are Notfoundin
Bones Bone marrow
Teeth CNS fluid drains into CSF
Lymphatic capillaries are very permeable due to overlapping
endothelial cells that form value flaps in walls of vessels These
flaps only open inward
Endothelial cells are anchored to surrounding tissue by collagen
filaments this prevents vessels from collapsing inwards due to the
interstitial fluidpressure
Lymphatic capillaries can drain fluid proteins pathogens debris even
cancer cells from tissues of thebody As lymph fluid runs through
the lymphnodes is cleanedup before reentering theblood system
in of intestine
Set of specialized capillaries called lutea
