Lymph nodes and what they do Lymph vessels route lymph fluid through nodes throughout the body. Lymph nodes are small structures that work as filters for harmful substances. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid.

Axillary lymph nodes are a group of nodes in your armpit that drain the lymph fluid from your breast and arm.

Lymph nodes are located throughout the body, distributed along the tubes of the lymphatic system. Places where you might be able to feel your swollen lymph nodes include your head and neck, under your chin, your arms, under your armpits, the area around your groin, and the back of your knees.

The lymph nodes in the pelvis lie along the internal, external and common iliac arteries (the main blood vessels that supply blood to the lower abdomen and trunk of the body).

The lymphatic system is a network of very small tubes (or vessels) that drain lymph fluid from all over the body. The major parts of the lymph tissue are located in the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils. The heart, lungs, intestines, liver, and skin also contain lymphatic tissue.

Lymph nodes are part of the lymphatic system, which is a network of tiny tubes that carry a colourless fluid called lymph through the skin and deeper parts of the body. Lymph fluid contains immune cells (lymphocytes) nutrients and waste materials.

The lymphatic system helps defend the body against illness-causing germs, bacteria, viruses and fungi. The system builds immunity by making special white blood cells (called lymphocytes) that produce antibodies which are responsible for immune responses that defend the body against disease.
653612
Lymph nodes contain lymphocytes, a type of white blood cell, and are primarily made up of B cells and T cells. B cells are mainly found in the outer cortex where they are clustered together as follicular B cells in lymphoid follicles, and T cells and dendritic cells are mainly found in the paracortex.

The lumbar lymph nodes are located in the region of the body between the diaphragm (a muscle in the lower rib cage that helps with breathing) and pelvis, known as the lumbar region. They are also called the lateral aortic lymph nodes. The nodes are part of the lymphatic system of the human body.

The affected lymph nodes are usually found in the neck or above the collarbone, and less commonly under the arms or in the groin. The lymph nodes are usually painless, firm, rubbery, and movable in the surrounding tissue.

Locations. No doubt, you are already aware of the lymph nodes found in your neck. However, you actually have hundreds of lymph nodes located throughout your entire body. Your tonsils are also classified as lymph tissues.
324291
The primary function of lymph nodes is the filtering of lymph to identify and fight infection. In order to do this, lymph nodes contain lymphocytes, a type of white blood cell, which includes B cells and T cells. These circulate through the bloodstream and enter and reside in lymph nodes. B cells produce antibodies.

Lymph nodes are your immune system's first line of defense, protecting you from things like bacteria or viruses that could make you sick. You have hundreds of the small, round, or bean-shaped glands all over your body.

Inguinal lymph nodes are lymph nodes located in the groin. Other lymph nodes are found in the armpits, neck, behind the ears, and under the chin. All lymph nodes are part of the lymphatic system, which includes lymph fluid, lymph vessels, bone marrow, and organs such as the thymus, adenoid, tonsil, and spleen.

Some lymph nodes are deep inside the body, such as between the lungs or around the bowel, to filter fluid in those areas. The lymph fluid slowly flows in from all around the body, making its way back to the chest.

A lymph node, or lymph gland is a kidney-shaped organ of the lymphatic system, and the adaptive immune system. A large number of lymph nodes are linked throughout the body by the lymphatic vessels. They are major sites of lymphocytes that include B and T cells.

People will commonly refer to the condition as "swollen glands." Cervical lymph nodes are simply lymph nodes located in the neck region. Lymph nodes are small structures located all over the body. They are part of the lymph system and have an important role in the immune system.
