LYMPHATICS
ANATOMY
The
intestitial spaces (space between cells) have a fluid. This
fluid
for its retrun to circulation has
a system of very fine
tubes
the lymphatics. They
are lined by a single
layer of
endothelial cells some lymphatics have contractile
muscle cells
in their walls
The
lymphatics drain into the regional lymph
glands (Fig.23.3)
after
the lymphatic fluid has been
filtered through the lymps
gland
another set of lymphatics that emerges from the hium
of
the
gland and the prepheral lymph finally
enters the veins
through the lymph in the thoracic
ducts.
6.1 LYMPHANGITIS
Infection of the skin and subcutanaeous tissue by Streptococcai
pyogenes produces severe inflammation
of the lymphatics resulting
in painful red streaks of lymphatics
and enlarged draining lymph
glands. Sometime
the draining lymph gland is
the site
of an
abscess.
6.1.1 Treatment
It is with bed rest and antibiotics.
Early incision and drainage
of abscess is required.
