|This is the first time we have mentioned the lymphatic
system so we need to consider an overview of the system to
understand how it works. Without going into a detailed description,
the following diagram shows the general makeup of a lymph node
and its afferent and efferent vessels. The lymphatic system is
part of the vascular system but it is very special in its
ability to take in larger particles than the vascular system
(i.e., bacteria, cancer cells, carbon). It is also part of
the immune system of our body and, therefore, serves as a
first line of protection against foreign bodies. This protection is
subserved by cells of the immune system.
In general, lymph is picked up peripherally from
|The last of the axillary contents are the axillary lymph
Lymph from the upper limb, shoulder and scapular regions, pectoral region
(including the mammary gland) and upper abdomen drain through the axillary
nodes. There are some 15 to 20 nodes usually arranged into to five groups. The groups consist of:
|The efferent lymph vessels from the right group of axillary nodes finally
forms into the subclavian lymphatic trunk which joins the jugular trunk
to form the right lymphatic duct which empties into the venous system at
the junction of the jugular and subclavian veins.
On the left side the subclavian lymphatic trunk empties into the thoracic duct and then into the venous system at the junction of the jugular and subclavian veins.
