  The Lymphatic System as a drainage system   (Site not responding. Last check: 2007-10-08)
Lymph capillaries branch and interconnect freely and extend into almost all tissues of the body except the CNS (Central Nervous System) and the avascular tissues such as the epidermis and the cartilage.
Thus the lymph leaving the node is both cleaner of debris and richer in lymphocytes.
Lymphatics from the lower portion of the body converge to form a dilated lymph vessel, the cisterna chyli, in the lumbar region of the abdominal cavity.

 Lymph node 2
Lymph nodes are small round or bean-shaped structures located at points along the lymphatic vessels.
The outer cortex consists primarily of numerous lymph nodules separated by diffuse lymphatic tissue, lymph sinuses and trabeculae.
Newly produced lymphocytes enter the lymph and are carried by the lymphatic vessels back to the venous system where they enter the circulation.

Principal architectonic and hystotopographic scheme of myocytes of afferent and efferent vessels is identical.
Attempt of researches to refer indicated layers to tunics of vessel by analogy with blood vessels (arteries and veins) does not have sufficient grounds as practically there is no bounds (elastic membranes) between tunics of lymph vessel.

Lymph nodules are scattered throughout loose connective tissue, especially beneath moist epithelial membranes such as those that line the upper respiratory tract, intestine, and urinary tract.
Lymph nodules appear to be strategically distributed to defend the body against disease organisms that penetrate the lining of passageways that communicate with the outside of the body.
Lymph nodes are found throughout the body the picture shows the positioning of some of the major groups of lymph nodes.

The lymph vessels are similar to veins, only instead of carrying blood as veins do, they circulate lymph to most tissues in the body.
Lymph nodes are about 600 small, bean-shaped collections of tissue found along the lymph vessel.
It is done by a surgeon under general anesthesia on lymph nodes in the interior of the body and under local anesthesia on surface lymph nodes where FNA biopsy is considered inadequate.

 Howstuffworks "What is lymph?"
All of the cells in your body are therefore bathed in lymph, and they receive their nutrients and oxygen from the lymph.
Lymph in the lymph vessels eventually reaches a lymph node -- there are about 100 nodes scattered throughout the body.
Lymph nodes filter the lymph and also contain large numbers of white blood cells (a big part of the immune system), which remove foreign cells and debris from the lymph.

 Factor Prompts Lymph Vessel Growth
Lymph drains from organs and tissues in the body, circulates through a vast network of vessels and filters through lymph nodes, the infection-fighting, bean-sized structures found throughout the body, occurring in clusters in the neck, arm pit, and groin.
The lymph vessels are thought to act as a conduit for breast cancer cells and other tumors as they spread in the body, so lymph nodes -- which are often the first place that cancer cells spread to after they escape from a tumor -- are often removed along with a tumor and analyzed.
Tumors have the ability to grow blood vessels to ensure a steady supply of nutrients -- a process known as angiogenesis -- but can't form lymph vessels to drain fluid.

It is unknown whether the characteristics of tumor cells in lymph vessels play an important role in the tumor progression of invasive ductal carcinoma (IDC) of the breast.
The purpose of this study was to investigate the significance of the characteristics of tumor cells in the lymph vessels in relation to the tumor progression in 393 IDC patients in comparison with well-known histological parameters.
The dimensions of lymph vessel tumor emboli were measured, and their structural features, nuclear atypia, and numbers of mitotic and apoptotic figures were also assessed.

In the case of lymphangioma circumscriptum, the underlying lesions constitute abnormal dilated lymph vessels involving the upper part of the dermis.
These cisterns are separated from the normal network of lymph vessels, but they communicate with the superficial lymph vesicles through vertical, dilated lymph channels.
Microscopically, the vesicles in lymphangioma circumscriptum are greatly dilated lymph channels that cause the papillary dermis to expand.

BOSTON, Sept. 6 (UPI) -- Researchers say they've determined immune cells known as macrophages are linked to the growth of lymph vessels in eyes.
Scientists at the Schepens Eye Research Institute found macrophages contribute to the growth of new lymph vessels, which aid in healing.
The researchers say the discovery might ultimately inspire innovative treatments for blinding eye diseases, as well as for other diseases, such as cancer, that rely on lymph vessels to spread abnormal cells throughout the body.
