When the body is invaded by foreign organisms, the swelling sometimes felt in the neck, armpits, groin, or tonsils,comes from the microorganisms trapped inside the lymph nodes. 当机体遭受外来微生物入侵,淋巴结会吞噬微生物,导致淋巴结富集的地方(如颈...
Lymph Circulation in Lymph Nodes Lymph arriving from the tissues or from a preceding lymph node in the chain, passes via the afferent lymphatics into the subcapsular sinus and then into the cortex, around the follicles, into the paracortical area and then into the medulla. Lymph in the medull...
Lymph nodesTumor cellsIn solid tumors, metastasis occurs through the dissemination of tumor cells in the bloodstream and the lymphatic system. In particular, lymph node infiltration gives useful prognostic information and represents one of the most important factors for selecting the type of clinical ...
Lymph nodes are strategically positioned throughout the body. All lymph, draining from tissues and organs, passes through lymph nodes before entering the bloodstream, which allows for efficient screening of incoming pathogens or tissue aberrations. It is now well established that the highly organized ...
Lymph nodes are small kidney- or bean-shaped organs, usually less than one inch (2.6 cm) in length. They are found in clusters of several nodes in many regions of the body, especially in the neck, armpits, trunk, and groin. The exterior of each lymph node is connected to many smaller...
The lymphatic vasculature collects and drains fluid and cells from the periphery through lymph nodes (LNs) for immune monitoring, and then returns lymph to the bloodstream. During immune responses LNs enlarge and remodel, featuring extensive growth of lymphatic sinuses (lymphangiogenesis). This LN lymp...
Lymph nodes are bean-shaped, encapsulated structures 2–10 mm in diameter that contain large concentrations of lymphocytes, FDCs and APCs (Fig. 2-14). Lymph enters a lymph node through several afferent lymphatic vessels. It then passes through the cortex, paracortex and medulla of the node, ...

Lymph returns proteins and excess interstitial fluid to the bloodstream. Lymph may pick up bacteria and transport them to lymph nodes, where the bacteria are destroyed. Metastatic cancer cells can also be transported via lymph. Lymph also transports fats from the digestive system (beginning in the...
For decades, physicians have known that many kinds of cancer cells often spread first to lymph nodes before traveling to distant organs through the bloodstream. New research from Children's Medical Center Research Institute at UT Southwestern (CRI) provi
