Lymph Node Function & Location [1]
Lymph nodes are small, bean-shaped organs that filter substances in your body. Cells that help fight infections make up your lymph nodes along with lymph tissue
The most well-known places where you’ll find lymph nodes are in your armpits, neck and groin.. A lymph node’s job is to filter substances in your lymph fluid, which is a collection of fluid that drains from your cells and tissues
The cells within your lymph nodes will attack, destroy and eliminate waste, especially foreign invaders, to help your immune system keep you healthy.. Your lymph nodes work closely with two body systems including your:

Lymph nodes (or lymph glands) are small lumps of tissue that contain white blood cells, which fight infection. They are part of the body’s immune system and filter lymph fluid, which is composed of fluid and waste products from body tissues
Lymph nodes are located throughout the body, including the neck, armpits, groin, around the gut, and between the lungs. Lymph nodes drain lymph fluid from nearby organs or areas of the body.
The lymph nodes filter out harmful substances and waste products. They also contain immune cells called lymphocytes that destroy cancer cells and bacteria.
Lymphatic system [3]
– The lymphatic system is our body’s ‘sewerage system’.. – It maintains fluid levels in our body tissues by removing all fluids that leak out of our blood vessels.
– The lymph nodes monitor the lymph flowing into them and produce cells and antibodies which protect our body from infection and disease.. – The spleen and thymus are lymphatic organs that monitor the blood and detect and respond to pathogens and malignant cells.
– When the lymphatic system is not formed well or has been damaged by surgery, radiotherapy or tissue damage, a swelling of a part of the body may occur (most commonly the legs or arms). When this swelling lasts more than about three months it is called lymphoedema.
Lymphatic System: Parts & Common Problems [4]
The lymphatic system is a network of tissues, vessels and organs that work together to move a colorless, watery fluid called lymph back into your circulatory system (your bloodstream).. Some 20 liters of plasma flow through your body’s arteries and smaller arteriole blood vessels and capillaries every day
The remaining three liters seep through the capillaries and into your body’s tissues. The lymphatic system collects this excess fluid, now called lymph, from tissues in your body and moves it along until it’s ultimately returned to your bloodstream.
– Absorbs fats from the digestive tract: Lymph includes fluids from your intestines that contain fats and proteins and transports it back to your bloodstream.. – Protects your body against foreign invaders: The lymphatic system is part of the immune system
Which of the following is the function of lymph?(a) Lymphs keeps the body cells moist(b) Lymphs takes lymphocytes and antibodies from the lymph nodes to the blood(c) Lymphs maintains the volume of the [5]
(b) Lymphs takes lymphocytes and antibodies from the lymph nodes to the blood. Hint: A clear-to-white fluid which is made up of White blood cells, especially lymphocytes, the cells that attack bacteria in the blood
– It transports oxygen, hormones, and nutrients to different parts of the body and removes metabolic waste from the cells.. – It transports antibodies and lymphocytes to the blood.
– Absorption of fats from the small intestine through lymphatic vessels.. – Prevents invasion of microbes and foreign substances inside the lymph nodes.

Treasure Island (FL): StatPearls Publishing; 2023 Jan-.. The lymphatic system is composed of lymphatic vessels and lymphoid organs such as the thymus, tonsils, lymph nodes, and spleen
The fluid that leaks from end-stage capillaries returns to the vascular system via the superficial and deep lymphatic vessels, which in turn drain into the right lymphatic duct and the thoracic duct. The right lymphatic duct travels on the medial border of the scalenus anterior muscle and drains the lymph from the right upper quadrant of the body
Structure and function of lymph nodes [7]
The lymphatic system is basically a channel that carries a clear or whitish fluid called the lymph. This lymph aids in clearing the tissues of infective organisms, toxins etc.
These are a network of tubes or vessels much like the blood vessels that cover all the tissues of the body.. The lymphatic channels get progressively smaller as they pass in to distant organs and tissues.
It branches into thinner tubes that progressively become thinner and thinner as they travel up to the fingers.. At the tips of the fingers the vessels may be the thinnest with places where they may be only a few cells thick

Lymph nodes [9]
Lymph nodes (or lymph glands) are small lumps of tissue that contain white blood cells, which fight infection. They are part of the body’s immune system and filter lymph fluid, which is composed of fluid and waste products from body tissues
Lymph nodes are located throughout the body, including the neck, armpits, groin, around the gut, and between the lungs. Lymph nodes drain lymph fluid from nearby organs or areas of the body.
The lymph nodes filter out harmful substances and waste products. They also contain immune cells called lymphocytes that destroy cancer cells and bacteria.
Lymph node [10]
|System||Lymphatic system, part of the immune system|. |Latin||nodus lymphaticus (singular); nodi lymphatici (plural)|
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
In the lymphatic system a lymph node is a secondary lymphoid organ. A lymph node is enclosed in a fibrous capsule and is made up of an outer cortex and an inner medulla.
Lymphatic system: Definition, anatomy, function, and diseases [11]
The lymphatic system is a network of vessels, nodes, and ducts that pass through almost all bodily tissues. It allows the circulation of a fluid called lymph through the body in a similar way to blood
This article details the lymphatic system, its role in the body, and what conditions can impair its function.. The lymphatic system is a network of vessels, nodes, and ducts that collect and circulate excess fluid in the body.
The lymphatic system returns excess fluid and proteins from the tissues that cannot return through the blood vessels. The fluid often collects in the tiny spaces surrounding cells, known as the interstitial spaces

Our editors will review what you’ve submitted and determine whether to revise the article.. lymph node, any of the small, bean-shaped masses of lymphoid tissue enclosed by a capsule of connective tissue that occur in association with the lymphatic vessels
They are typically found concentrated near junctions of the major lymphatic vessels, most prominently in the neck, groin, and armpits.. Each lymph node is divided into two general regions, the capsule and the cortex
The cortex is further divided into two functional areas: the outer cortex and inner cortex, or paracortex. These regions surround an inner medulla, which consists primarily of activated antibody-secreting plasma cells.
What does the lymphatic system do? (5 functions) [13]
The lymphatic (or lymph, for short) system is a network of vessels, tissues, and organs that work together to maintain fluid balance, remove waste products and toxins, and support the immune system. Fluid balance – the lymphatic system collects excess fluid, called lymph, from the body’s tissues and returns it to the bloodstream
Immune response – the lymphatic system plays a crucial role in the body’s immune defence. Lymph contains immune cells, such as lymphocytes, which help identify and destroy pathogens (disease-causing microorganisms) and foreign substances
Absorption of fats – the lymphatic system absorbs dietary fats and fat-soluble vitamins from the digestive system. Specialised lymphatic vessels called lacteals in the small intestine take up these substances and transport them to the bloodstream for distribution to the body’s cells.

Author: Maria Yiallouros, Erstellt am 2022/09/23, Editor: Maria Yiallouros, Last modification: 2022/09/23 https://kinderkrebsinfo.de/doi/e261534. The lymphatic system consists of all lymphatic vessels and lymphoid organs
Hence, rather than representing a single organ, the lymphatic system comprises a circulatory network of vessels and lymphoid tissue and cells in every part of the body. It works together closely with the blood-producing (haematopoietic) system in the bone marrow, thereby playing a vital role in immune responses to protect the body from various pathogens
The lymphatic system with its vessel network is – apart from the circulatory system, with which it is closely connected – the most important transport system in the human body.. The human body produces about two litres of lymph every day

The white patches on either side of the throat in this picture are signs of tonsillitis. The tonsils are small structures in the throat that are very common sites of infection
The patches consist of large amounts of dead bacteria, cellular debris, and white blood cells; in a word, pus. Children with recurrent tonsillitis may have their tonsils removed surgically to eliminate this type of infection
It also includes a network of vessels that transport or filter the fluid known as lymph in which lymphocytes circulate. Figure (PageIndex{2})shows major lymphatic vessels and other structures that make up the lymphatic system
