Lymph nodes are an important part of the human body and have an important function in the immune system that is facing diseases, and because of its importance, we will talk about them in more detail in this article.
Lymph nodes
There is no doubt that lymph nodes play an important role in the immune system of the human body, which are round blocks form the body except the brain, and the total number of about (500-600) lymphoid gland distributed throughout the body, Heavily in the armpits, and in the upper thighs and neck as well.
It can be said that the lymph nodes are divided into two parts: some of which are close to the skin, and can be touched and feel by pressure fingers lightly: five groups are located under the right armpit, and the left, and estimated about twenty lymph nodes, and also have glands below the jaws , Behind the ear and bottom, and in the lower part of the neck, and at the front of the shoulder. There are about 300 lymph nodes in the area, both longitudinal and transverse, to protect the body from viruses.
The second part is that which is inside the skin. These glands can not be touched. They are located inside the human chest between the lungs, in the area near the aorta in the human abdomen, in the pelvic area, in the inguinal area, and also in parts of the digestive system, spleen, Bone, where we can only see it through radiology and central tomography.
As for the presence of lymph nodes in the neck area, there is no doubt that this region is considered the most vulnerable to viruses, which enter the body through three entrances: the pharynx, and the nose, in addition to the mouth. We can say that every region of the human body has a gland where the lymph vessels flow.
The normal size of the lymph nodes is less than 1 cm; if it exceeds this normal size, it may be inflated because of a specific cause, either because of a bacterial infection or a viral infection, or because of infections such as: boils, cancers or abscesses Skin, or other diseases such as: AIDS or AIDS, and here is the inflation in different parts of the body, not in one area, and the causes of inflation also: the incidence of arthritis, which leads to swelling of the lymph node, and once cured From any infection that has hit the body, this inflation immediately disappears.
