Lymph (from Latin, lympha, meaning "water")[1] is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to be recirculated. At the origin of...
iii) Lymph Nodes As lymph flows through the lymphatic vessels, it passes through the lymph nodes. The lymph node is the major site for the interaction of lymphocytes with antigen during a primary adaptive response. Antigen that finds its way past the body’s innate defenses and escapes MALT ...
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...
淋巴结是小小的,形如豆状分布于全身的腺体。它们是淋巴系统的一部分,在人体组织和血液之间运输淋巴液、营养物质和废物。 淋巴系统是人体免疫系统的重要组成部分。淋巴结在淋巴液流经它们的过程中起到过滤淋巴液,诱捕细菌、病毒和其它外来物质的作用,然后这些物质被淋巴细胞...
In theory, thesentinel lymph nodemethod not only implies the benefits from alymph node dissection, but also reduces its detriments. Sentinel lymph node (SLN) is the first lymph node into which aprimary tumordrains, making it the most likely of all the nodes in the draining basin to contain...
The lymph leave the lymph node via? Lymph Nodes: Lymph nodes are connective tissue structures within the lymphatic system that clean and filter lymph as it flows through the body. These nodes contain many lymphocytes which help defend against pathogens that have entered circulation. Answer and Expl...
Enlargement of lymph nodes: Swelling may cause your lymph nodes to grow in size, ranging from the size of a pea or kidney bean to even larger. Runny nose, sore throat, fever, and other indications of an upper respiratory infection: Swollen lymph nodes in your neck may signal an infection...
your lymph nodes and draw up a clear fluid called lymph from around your cells. Your lymph fluid carries waste (like what's left of a cell after it dies) that has been removed from your cells and trapped bacteria and viruses to your lymph nodes before it flows back into your bloodstream...
Lymph nodesare the “charcoal filtration system” of the body. In fact, if the thyroid cancer does not spread to lymph nodes, the likelihood or potential for it to spread to other sites in the body is very low. Because of this, the evaluation, detection and removal of thyroid cancer invo...
the lymph nodes awaiting any invading pathogens. When the lymphocytes are exposed to an infection, it produces antibodies against the invader proteins. This allows the lymphocytes to exit the node and target the site of infection. Other immune cells are also recruited to the lymph node at the ...
