![]() So if lymph nodes in the throat are swollen, it’s an indication of cold or viral infections, if swollen in the groin area, an indication of sexually transmitted disease, etc. The clusters of lymph nodes are distributed throughout the body, in order to filter out invading cells in the vicinity, which makes perfect sense. This is because the lymph vessels generally drain into blood vessels, from where the waste material is transported by blood to the liver and kidneys (sewage treatment plants) for breakdown and elimination. ![]() They are also compared to sewerage drains as they drain out the waste in the body. That is why the lymph vessels, lymphatic fluid and lymph nodes are compared to filters as they filter out invading pathogens. They are basically looking for swollen cervical lymph nodes.) (You may remember doctors trying to feel the underside of your throat when you have a fever. It’s a clear indication that there are invaders – infections or disease-causing pathogens in the body. That is when, or that is why, the lymph node gets swollen up. Here, more white blood cells (more police) try to attack or stop the invaders, causing a build-up of cops and criminals – white blood cells and invading cells at the lymph node. If white blood cells (patrol police) are not able to destroy the infiltrating pathogens, they are able to get away but eventually arrive at check-points called lymph nodes. That is, invading cells attach themselves or penetrate blood vessels and lymph vessels in an attempt to harm the body. Pathogens like viruses and bacteria, cancerous cells and other toxic materials are like criminals that get onto the highway and try to harm the body. The lymph vessels are like the highway in which white blood cells, that act as patrol police, flow through. The working of the lymphatic system can be best understood by comparing it with the criminal-policing system. Overall, there are approximately 600 clusters estimated to be present in a normal, healthy, adult human body. ![]() Other than these, there are several clusters deep inside the body which cannot be seen or felt. These can be felt to the touch by a doctor. They are close to the surface of the skin, behind the ears (auricular lymph nodes), in the neck (cervical), near the collar-bone (supraclavicular), upper chest (subclavian), chest (pectoral), at the armpits (axillary), at the elbow (epitrochlear) and the groin (inguinal). Clusters of lymph nodes are present throughout the body. The lymphatic system primary consists of thin, tubular, vein-like ‘lymph vessels’, in which a thin, clear fluid called the ‘lymphatic fluid’ flows, and small, kidney-bean shaped, lymph nodes. It’s part of the body’s immune system and is responsible for maintaining a good level of immunity against disease. Yet it’s one of the most important systems for our overall health and well-being. ![]() To know more about this, we need to understand what is the lymphatic system is and how does it work? What is the lymphatic system?Īmong all the body-systems, people have the least awareness about the lymphatic system. ![]() That is why more tests are done to confirm or rule out cancer(s). In the same way, absence of such markers does not mean, there is no cancer. However, these are not enough to confirm cancer. The lymph node could be large in size, irregular in outline, firm or hard, or rubbery or not very mobile. There are some physical markers in which case cancer is suspected. The simplest answer would be – hard to say! While some general indications are there, these are not enough to confirm or rule out cancer. December 13 07:04 2021 by admin Print This Article ![]()
