Lymph vessels and nodes of posterior abdominal wall
I had a post about lymph system a while ago => https://plus.google.com/112847310756615438437/posts/ibpgsNnqVPm
- so I won't bore you with the details too much.
Let's summarize in a few words:
A lymph node
is an oval-shaped organ of the lymphatic system, distributed widely throughout the body including the armpit and stomach and linked by lymphatic vessels. Lymph nodes are major sites of B, T, and other immunity cells. Their function is to filter out all the dead bacteria, viruses, and other dead tissue from the lymphatic fluid and eliminate it from the body. They are packed tightly with the white blood cells called lymphocytes and macrophages.
Lymph nodes also have clinical significance. They become inflamed or enlarged in various infections and diseases which may range from trivial, such as a throat infection, to life-threatening such as cancers. In the latter, the condition of lymph nodes is so significant that it is used for cancer staging, which decides the treatment to be employed, and for determining the prognosis. When swollen, inflamed or enlarged, lymph nodes can be hard, firm or tender.

are structures of the lymphatic system that transport fluid away from tissues. Lymphatic vessels are similar to blood vessels, but they don't carry blood.
