The lymph nodes are one of the most important elements of the immune system in the human body. The function of the lymph nodes is to defend any foreign body entering the body. These glands are the strong bulwark of the human body and act to fight all types of infections and infections that can infect the body Human.
The lymph nodes are shaped in a round or oval shape. The lymph nodes are distributed throughout the body, and they are intertwined with a regular network problem, called the “chain.” The blood vessels are the link between them. The lymph nodes also contain many of the lymph nodes, The immune cells inside, and these cells work on the production of proteins that fight and respond to microbes, viruses.
Sites and locations of lymph nodes
Lymph nodes are located in various areas of the human body, some of which are directly below the skin, some deep within the body in the organs, and usually the lymph nodes located near the surface of the skin, invisible to the naked eye, and can not be distinguished by simple senses such as touch, Lymphatic fluid flows at the end of its way into the veins.
Some lymph nodes are called the human body. The cervical lymph nodes are located in the neck area and are distributed in the face. Some of the glands are located behind the ear. There are also the axillary lymph nodes under the armpit. The lymph nodes are located in the thigh, The skin is direct, and what is deep in the thigh itself.
Although multiple lymph nodes are distributed in the lymphatic channels, these glands, which contain many immune cells, are not present in the brain region.
Function of the lymphatic system
The lymphatic system works with the circulatory system, where the lymph nodes have channels in which these glands are present. The lymphatic fluid is transported through it. The fluid is transferred to the kidneys, which contains protein and fat. This system helps the blood circulation to transfer the nutrients to the cells. The lymph nodes also contain immune systems, which in turn act to maintain the body’s immunity and health, such as the spleen, bone marrow, tonsils, lemongrass, and zygote. The bone marrow is a device that produces lymphocytes.
