Just as there is the blood circulatory system in which the arteries deliver blood to the tissues throughout the body and the veins return it to the heart, there is a lymphatic system in which tissue fluid is drained from all areas of the body. These lymphatic vessels drain into regional centers where there are clusters of lymph nodes that strain the lymphatic fluid. The fluid is eventually returned to the blood system. The lymphatic system is a major part of the immune system and is responsible for the initial response to combat infections. Cancer can spread by way of the lymphatic system. Success or failure of treatment often depends on whether the regional lymph nodes are involved with the cancer.
accumulations of lymph tissue found in locations throughout the body of mammals and birds where noxious substances such as bacteria and toxins are removed. Lymph nodes play a role in the formation of antibody – specialized proteins produced by the immune system that respond to foreign substances introduced into the body.
Small bean-shaped organs found in the neck, groins, armpits and other parts of the body which are part of the immune system. They can become enlarged due to infection and cancer.
A small, oval organ located within the lymphatic vessel network.
Small bean-shaped structures scattered along the lymphatic vessels, particularly in the neck, armpit and groin. They filter the lymph to remove bacteria and other harmful agents to prevent them from entering the bloodstream. Lymph nodes also produce lymphocytes, a type of white blood cell. Also called lymph glands (although they are not true glands). Lymph node negative test results show no cancer cells in the lymph nodes. Lymph node positive test results show that cancer cells are present in the lymph nodes.
Pea-sized, oval-shaped structures found along lymphatic vessels. Lymph nodes filter out waste and fluids from lymph.
Gland in the body that filters the lymph.
small oval or round gland that makes up part of the immune system that removes bacteria and foreign particles from the body.
A small organ that is a component of the lymphatic system and consists of lymphocytes, macrophages, and dendritic cells. The lymph nodes filter lymph from peripheral nodes, and ultimately empty into the thoracic duct.

a round, oval, or bean shaped structure localized in clusters along the lymphatic vessels, with a distinct internal structure including specialized vasculature and B- and T-zones for the activation of lymphocytes
This is a gland that is composed of a collection of lymphocytes that is connected to lymphatic vessels that circulate the lymph in the body. These are basically filters that are looking for something that has entered the body like a germ, virus, pollen, mold, chemical. It is in this gland that the immunity response is begun. This often causes swelling of the gland because many of the lymphocytes are reproducing and increasing their numbers to assist in the battle that will eliminate the foreign interloper.

A small collection of tissue along the lymphatic system which acts as a filter. White cells and cancer cells, in particular, collect in lymph nodes. They are found in the neck, the armpit, the groin and many other places. Lymph nodes are also known as glands.
small, bean-shaped organ that stores special cells that can trap cancer cells, bacteria, or other foreign bodies as they move through the body
Bean-sized organ (‘gland’) found throughout the lymphatic system constituted by lymphocytes and other cells responsible for immune defense.
Bean-shaped immune system organ forming a site of lymphatic filtration. Grossly comprised of a capsule, cortex and medulla. Underlyingthe capsule is the subcapsulary sinus containing scattered reticular cells, macrophages,circulating lymphocytes and a boundary of edothelial cells. The cortex is comprised of more exterior follicles and a deep cortical zone ( paracortex) without follicles. Follicles lacking germinal centers are called primary, those with are called secondary. The medulla is composed of densely cellular medullary cords and less densely populated medullary sinuses. Medullary sinuses are continuous with efferent lymphatic vessels found in the lymph node's hilum.
Small structures (from pinhead-size to olive-size) found throughout the body that produce lymphocytes and monocytes, which help protect the body from invasion by bacteria or other organisms.
Secondary immune organs distributed at discrete locations throughout the body. These organs play a central role in the activation and trafficking of immune lymphocytes in the body.
Small oval structures that filter the lymph and fight infection. Found in the groin, abdomen, neck, armpit and other sites.
A rounded mass of lymphatic tissue that is surrounded by a capsule of connective tissue. Lymph nodes are spread out along lymphatic vessels and contain many lymphocytes, which filter the lymphatic fluid (lymph). Lymph nodes are part of the body’s immune system.
A rounded mass of lymphatic tissue that are found throughout the body. Lymph fluid passes through the lymph nodes, which filter out bacteria, cancer cells, and toxic chemicals.
Glands found throughout the body along lymphatic channels which defend the body from bacteria or other foreign invaders. If cancer cells are found in the lymph nodes, they are an indication that the cancer may have spread beyond the breast.
an oval or round body located in the lymphatic system (all over the body) that supplies lymphocytes to the blood stream and removes bacteria from the body.
a small, bean-sized organ located throughout the body, with concentrations in the neck, groin and armpits. Lymph nodes filter out antigens and are the site of antigen presentation and immune activation. The lymph nodes are a reservoir site for HIV.

small bean-sized organs made up mostly of densely packed LYMPHOCYTES, LYMPH FLUID and connective tissue. Clusters of lymph nodes are widely distributed in the body and are essential to the functioning of the immune system. They are the main sites where acquired immune responses are launched (see IMMUNE SYSTEM and NAIVE T CELL). Lymph nodes are connected with each other, other lymphoid tissue and the blood by the LYMPHATIC VESSELS.

An oval structure which is the site where lymphatic vessels come together.
An oval or round nodule located in many areas throughout the body that contain cells called lymphocytes. The lymph node acts as a "filter" against infectious agents such as bacteria and to some degree malignant tumor cells that come from areas of the body that are close to the lymph node.
Small glands that release cells to defend the body against harmful foreign particles
a round mass of lymphatic tissue, also called a lymph gland. Lymph nodes are located all over the body, along the lymphatic system. This system is a network of tubes that carry lymph, a clear fluid containing white blood cells. Lymph nodes filter the lymph fluid, while the white blood cells (also known as lymphocytes) help fight infection and cancer.
Also sometimes referred to as lymph glands, lymph nodes are small rounded or bean-shaped masses of lymphatic tissue surrounded by a capsule of connective tissue . Lymph nodes are located in many places in the lymphatic system throughout the body. Lymph nodes filter the lymphatic fluid and store special cells that can trap cancer cells or bacteria that are traveling through the body in the lymph fluid. The lymph nodes are critical for the body's immune response and are principal sites where many immune reactions are initiated. During a physical examination, doctors often look for swollen lymph nodes in areas where lymph nodes are abundant, including the neck, around the collarbone , the armpit ( axilla ), and the groin .
