The tissues and organs that produce, store, and carry white blood cells that fight infection and other diseases. This system includes the bone marrow, spleen, thymus, lymph nodes and a network of thin tubes that carry lymph and white blood cells. These tubes branch, like blood vessels, into all the tissues of the body.
This system is comprised of lymph nodes, lymph vessels, and lymph glands and transports a watery clear fluid called lymph.
A network of vessels that transfers lymph from the tissue fluids to the bloodstream. Lymph nodes occur at intervals along the lymphatic vessels.
All of the vessels and structures that carry lymph from the tissue to the blood.
A series of vessels which transport lymph from the tissues through the lymph nodes and into the bloodstream.
The network of vessels and organs through which the body’s immune system operates.
Network of capillaries, vessels, ducts, nodes, and organs that help to maintain the fluid environment of the body and to protect the body by producing lymph and conveying it around the body. Lymphatic capillaries unite to form lymph vessels, which have numerous valves to control lymph flow and nodes to filter It. The lymphatic vessels lead to two large vessels: the thoracic duct and right lymphatic duct, both in the neck, from which the lymph drains into the bloodstream. Specialized lymph organs include the spleen, thymus, and tonsils.
Comprised of the main lymphatic duct, draining lymph from the upper right body quadrant and returning it to the bloodstream via the right subclavian vein.
A drainage system of vessels, glands, and ducts that channels a body fluid called lymph from tissues all over the body back into the bloodstream. The lymphatic system is a major part of the body’s immune system, which fights infection and cancer.
A network of vessels that conveys electrolytes, water, proteins, etc., in the form of ‘lymph from the tissue fluids to the bloodstream. It consists of fine blind-ended lymphatic capillaries, which unite to form lymphatic vessels. At various points along the lymphatic vessels are lymph nodes. Lymph drains into the capillaries and passes into the lymphatic vessels, which have valves to prevent backflow of lymph. The lymphatics lead to two large channels, the thoracic duct and the right lymphatic duct, which return the lymph to the bloodstream via the innominate veins.
The system that includes all the lymph vessels that collect tissue fluid and return it to the blood (lymph capillaries, lacteals, larger vessels, the thoracic duct, and the right lymphatic duct), the lymph nodes and nodules, the spleen, and the thymus.
A network of vessels that carry a clear fluid called lymph throughout the body.
Body system made up of lymph, lymph nodes, the thymus gland, the spleen, and lymph vessels. It carries waste and impurities away from the cells and protects the body from disease by developing immunities and destroying disease-causing microorganisms.
The tissues and organs that produce, store and carry white blood cells that fight infections and other diseases. This system includes the bone marrow, spleen, thymus, lymph nodes and lymphatic vessels (a network of thin tubes that carry lymph and white blood cells). Lymphatic vessels branch, like blood vessels, into all the tissues of the body.
A network of vessels that collect fluid from the tissues of the body and return it to the bloodstream.
Network of channels carrying lymph, a clear fluid, around the body, helping to protect the body from disease and to expel toxins.
A complex interweaving of conduits, encompassing vessels, clusters of lymph nodes, the sentinel tonsils, the vital thymus gland, and the resilient spleen, constitutes a remarkable network. This intricate assembly assumes the noble duty of facilitating the transportation of vital fluids and nourishment towards the very lifeline of our existence, the bloodstream. Additionally, it serves as the sanctum where select blood cells, integral components of our body’s formidable immune system, mature and flourish.
The lymphatic system consists of a network of vessels (lymphatic vessels) that carry lymph from tissues throughout the body back to the bloodstream. It’s an integral part of the immune system, playing a key role in protecting the body from infections and cancer. Additionally, it aids in absorbing fats from the intestines.
Every tissue in the body is surrounded by lymph, a clear fluid originating from the bloodstream. While a significant portion of this fluid re-enters the bloodstream via capillary walls, the rest is channeled to the heart through the lymphatic system.
Lymph is propelled through the lymphatic vessels by physical movement. When muscles contract during activity, they squeeze these vessels. Valves within the vessels guarantee that the lymph consistently flows in the right direction.
Lymph nodes are located along the lymphatic vessels and serve as points through which lymph flows. These nodes filter the lymph, capturing or eliminating infectious agents or other foreign substances. The spleen and thymus are also part of the lymphatic system, and they produce lymphocytes, which are white blood cells that combat infections or harmful cells.
When infection or inflammation arises in a specific region of the body, the associated lymph nodes might swell and become sensitive due to the white blood cells inside them fighting the responsible agents or cells. In cases of especially severe infections, the lymphatic vessels connected to these nodes can also get inflamed.
When a lymphatic vessel is blocked, possibly by worms or cellular debris, lymph accumulates in the surrounding tissues, resulting in lymphoedema.
Cancer often metastasizes to other areas of the body via the lymphatic system. When a primary tumor infiltrates the lymphatic vessels, tumor cells can detach and enter these vessels. These cells might then settle in nearby lymph nodes, where they can develop into secondary tumors. For instance, in breast cancer, cells from the primary tumor can migrate to the lymph nodes located in the armpit.
The lymphatic system consists of vessels and glands, including the thoracic duct, that collect lymph from body tissues and return it to the bloodstream. Lymph is a near-colorless fluid originating from blood, flowing through capillaries to surround body cells, supplying them with nutrients. It’s then drained by both veins and small vessels known as lymphatic vessels, which have valves to ensure lymph flows in one direction. Scattered along these vessels are glands or lymph nodes that filter the lymph before it rejoins the bloodstream through the thoracic duct, located at the neck’s base on the left side. If there’s an infection in an area, the nearby lymph nodes work to prevent the infection from entering circulation. In doing so, they might become inflamed, swollen, and sometimes even develop into abscesses.
