Lymph Nodes Locations

Lymph nodes locations are small, bean-shaped organs of the lymphatic system. The lymphatic system circulates the interstitial fluid called lymph nodes locations to the body cells and tissues. It also collects waste substances from the bloodstream. 

lymph nodes locations contains white blood cells (WBCs) as its major component. It is more or less similar to the blood plasma. Lymph nodes, on the other hand, are made up of various types of cells and tissues, of which WBCs and lymphoid tissues are more abundant. 

Lymph nodes locations

The size of lymph glands in adults is smaller, as compared to those in children between the age group 10 - 12. lymph nodes locations is located in the lymphatic system, which is distributed throughout the body. It can be present independently or in groups. About 500 - 600 lymph nodes are present in the human body. Groups of lymph nodes locations are present in the neck, collarbone, under the arms (armpit), and groin. Following is the list of lymph nodes with their placement in the body.

Cervical lymph nodes locations These lymph nodes are located in the head and neck region. Basically found deep in the neck, behind the ears and bottom of the jaw. In total, they are six in number. They draw lymph from the scalp, face, nasal cavity and pharynx.

Supraclavicular lymph nodes locations: Situated along the collarbone or clavicle, they drain lymph from the parts of the collarbone and the upper parts of the chest. These nodes can also be considered a part of the cervical lymph nodes.

Axillary lymph nodes locations: These nodes are present in the armpit area. They are divided into two types, namely, superficial and deep lymph nodes locations. They drain lymph from arm, walls of thorax and breast.

Mediastinal lymph nodes locations They are present in the central part of the chest, between the lungs. It drains from the middle section of chest cavity, parts of the upper abdomen and lungs. 

Supratrochlear lymph nodes locations: These nodes are present on the arms just above the elbow joint. They drain from the fingers, hand on the ulnar side of the arm and superficial areas of the forearm.

Mesenteric lymph nodes locations: - Distributed in the lower abdomen, they lie close to the small intestine. They drain cecum, jejunum, ileum, colon and upper part of rectum.

Inguinal lymph nodes locations These nodes are located in the groin area. They may be superficial or deep lymph nodes. They receive lymph from the genital areas, buttock, anus, abdominal wall and legs. 

Femoral lymph nodes locations: Located in the upper thigh portion along the femoral veins. They are immediately below the inguinal lymph nodes. They drain from some of the genital parts, buttock, thigh and the medial side of the leg. 

Popliteal lymph nodes: These lymph nodes are present in the knee area called popliteal fossa. There are two sets of popliteal lymph nodes some are present beneath the popliteal fascia and some are found between the popliteal artery and the posterior surface of the knee joint. They drain from the knee, thigh, calf and feet.

Functions of Lymph Nodes

As already mentioned, lymph nodes are essential organs of the immune system and play a crucial role in the normal functioning of the system. Here are the major functions of lymph nodes:
