The
preaortic lymph nodes
lie in front of the
aorta
, and may be divided into
celiac lymph nodes
,
superior mesenteric lymph nodes
, and
inferior mesenteric lymph nodes
groups, arranged around the origins of the corresponding arteries.
The celiac lymph nodes are grouped into three sets: the
gastric
,
hepatic
and
splenic lymph nodes
. These groups also form their own subgroups.
The superior mesenteric lymph nodes are grouped into three sets: the
mesenteric
,
ileocolic
and
mesocolic lymph nodes
.
The inferior mesenteric lymph nodes have a subgroup of
pararectal lymph nodes
.
The preaortic lymph nodes receive a few vessels from the
lateral aortic lymph nodes
, but their principal afferents are derived from the organs supplied by the three arteries with which they are associated?the
celiac
,
superior
and
inferior mesenteric arteries
.
Some of their efferents pass to the
retroaortic lymph nodes
, but the majority unite to form the
intestinal lymph trunk
, which enters the
cisterna chyli
.
