Forms a vital part of the body’s immune system and helps defend against bacteria and other intruders. The lymphatic system is a collection of lymph vessels and glands. Lymphatic tissue found in all organs and lymph nodes represents the cellular component, whereas the vascular component is represented by the lymph vessel and lymph duct systems. This second article in a six-part series explains the primary and secondary lymphoid organs and their clinical significance and structure. The thoracic duct, on the other hand, is comparatively longer and may attain the length of up to 45 cm in human adults, whereas its average diameter is about 5 mm. Citation: Nigam Y, Knight J (2020) The lymphatic system 3: its role in the immune system. The lymphatic system is a part of the circulatory system [also called subsystem of the circulatory system] that is formed by a network of network of vessels [other than arteries and veins], tissues, and organs. Tonsils play a role in the body’s immune defense response to inhaled or ingested bacteria and viruses. The lymphoid organs’ purpose is to provide immunity for the body.

Its major function is to drain lymph from the upper right section of the trunk; the right side of the head and neck; and the right arm. The lymphatic system occurs throughout the body and is made up of small glands called lymph nodes, which are connected to each other by a series of vessels called lymphatics. Lymphatic … The function of lymphatic tissue is drainage of excess tissue fluid and defense. The lymph comprises lymph plasma, lymph corpuscles and lymphoid organs. It is the first line of defense against disease. This network of vessels and nodes transports and filters lymph fluid containing antibodies and lymphocytes (good) and bacteria (bad). Anatomy of the Lymphatic System. For example, the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer’s patches) and throat (adenoid tonsils, palatine and tubal tonsils), to name a few, all represent lymphatic organs. It has 3 main roles: Fluid balance: return tissue fluid to the blood; Protection from infection: produce white blood cells lymphocytes; Absorption of fats: transport digested fats from villi to blood stream; 1.

Functions of the Lymphatic System. The lymphatic system consists of the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer’s patches) and throat (adenoid tonsils, palatine & tubal tonsils), It is a part of your immune system, It has many functions, It can protect your body from illness-causing invaders, maintain body fluid levels, absorb digestive tract fats and remove cellular … Lymphatic System.

Lymph nodes are classified as "secondary" lymphoid organs, with the primary lymph organs being the thymus gland , tonsils , spleen , and bone marrow . Lymphatic dysfunction is a poorly working lymphatic system. Lymphocytes are a critical part of the body's immune response. :- 6. travel along with blood vessels. The main functions of the lymphatic system are helping fight infection and draining excess fluid from tissues. Lymphatic organs are typically composed of clumps of lymphocytes and other cells arranged within a network of connective tissue and include the thymus, tonsils, spleen and lymph nodes. The lymphatic system is a circulatory system for lymphatic fluid, comprising a network of conduits called lymphatic vessels that carry the fluid in one direction toward the heart. Lymphatic system (anterior view) The lymphatic system is a system of specialized vessels and organs whose main function is to return the lymph from the tissues back into the bloodstream.. Lymphatic system is considered as a part of both the circulatory and immune systems, as well as a usually neglected part of students' books. The lymph fluid only travels in one direction.

Let’s start with one that many would not associate with the lymphatic system – Bone Marrow. Like the veins of the circulatory system, lymphatic capillaries and vessels move lymph with very little pressure to help with circulation. The main function of the system is Maintainfluid balance in the body by collecting excess fluid depositing them in the bloodstream.
