Lymphatic System Anatomy While in the thymus, T lymphocytes do not respond to pathogens and foreign organisms. After maturation, they enter the blood and go to other lymphatic organs, where they help provide defense. Structurally, the thymus is similar to the spleen and lymph nodes, with numerous lobules and cortical and medullary elements.

What are Secondary Lymphoid Organs? Spleen, lymph nodes, adenoids, tonsils are the encapsulated secondary lymphoid organs. Mucosa associated lymphoid tissue distributed throughout the body such as alimentary canal, respiratory and urinogenital tracts etc. are the diffused secondary lymphoid regions.

Organs of the Immune System: Your Shield Against Diseases The major organs of the immune system are bone marrow, thymus, spleen and lymph nodes. These organs produce lymphocytes required to destroy bacteria, virus, tumor cells, etc.This article dwells on these major immune system organs that protect the human body from infections.-Cells: The main function of T-cells or T lymphocytes is intensifying immune system responses. They do this by secreting specialized factors, which in turn activate other white blood cells, to fight off infections. T-cells are again subdivided into different types.

Lymphatic system The lymphatic system is part of the circulatory system and a vital part of the immune system, comprising a network of lymphatic vessels that carry a clear fluid called lymph (from Latin lympha meaning water) directionally towards the heart.ymphocytes are concentrated in the lymph nodes. The spleen and the thymus are also lymphoid organs of the immune system. The tonsils are lymphoid organs that are also associated with the digestive system.

Immunology/Organs of the Immune System The organs of the immune system are positioned throughout the body. They are called lymphoid organs because they are home to lymphocytes, small white bloodcells that are the key players in the immune system.here are two groups of immune system organs. 1  Primary (central)--organs where immature lymphocytes develop. 2  Thymus. 3  Bone marrow. 4  Secondary (peripheral)--tissues where antigen is localized so that it can be effectively exposed to mature lymphocytes. 5  Lymph nodes. 6  Appendix. 7  Peyer's Patches (of GI tract). 8  Tonsils. 9  Adenoids.

Immune Organs - organs of the immune system Note: you may find bone marrow, thymus gland, spleen and lymph nodes in the same group (primary organs)- it depends on the author, the book and the importance of the role an specific organ plays in the immune system in that given context.alking about the immune organs (i'll get back to the immune system cells later): Primary Organs: Thymus-located beneath the breast bone.

- Lymphocytes. Lymphoid tissue is made up of several types of immune system cells that help the body fight infections. Most of the cells in lymphoid tissue are lymphocytes, a type of white blood cell. The main types of lymphocytes are B lymphocytes (B cells) and T lymphocytes (T cells).

Autoreceptor An autoreceptor is a receptor located on presynaptic nerve cell terminals and serves as a part of a feedback loop in signal transduction. It is sensitive only to those neurotransmitters or hormones that are released by the neuron in whose membrane the autoreceptor sits. Canonically, a presynaptic neuron releases the neurotransmitter across a synaptic cleft to be detected by the receptors on a postsynaptic neuron. An autoreceptor will detect this neurotransmitter from its position on the presynaptic membrane.

Lymphoid tissue Lymphoid tissue: Lymphoid tissue, cells and organs that make up the lymphatic system, such as white blood cells (leukocytes), bone marrow, and the thymus, spleen, and lymph nodes. Lymphoid tissue has several different structural organizations related to its particular function in the immune response. The most highly organized lymphoid tissues are in the thymus and lymph nodes, which are well-defined encapsulated organs with easily identifiable architectures.

LYMPHATIC SYSTEM AND IMMUNITY. Lymph organs include the bone marrow, lymph nodes, spleen, and thymus. Bone marrow contains tissue that produces lymphocytes. B-lymphocytes (B-cells) mature in the bone marrow. T-lymphocytes (T-cells) mature in the thymus gland.he lymphatic system is composed of lymph vessels, lymph nodes, and organs. The functions of this system include the absorbtion of excess fluid and its return to the blood stream, absorption of fat (in the villi of the small intestine) and the immune system function.

Lymph node A lymph node or lymph gland is an ovoid or kidney-shaped organ of the lymphatic system, and of the adaptive immune system, that is widely present throughout the body. They are linked by the lymphatic vessels as a part of the circulatory system. Lymph nodes are major sites of B and T lymphocytes, and other white blood cells. Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles and cancer cells. Lymph nodes do not have a detoxification function, which is primarily dealt with by the liver and kidneys. In the lymphatic system the 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. Lymph nodes also have clinical significance. They become inflamed or enlarged in various diseases which may range from trivial throat infections, to life-threatening cancers. The condition of the lymph nodes is very important in cancer staging, which decides the treatment to be used, and determines the prognosis.

Lymphatic system The lymphatic system consists of lymphatic organs, a conducting network of lymphatic vessels, and the circulating lymph. The thymus and the bone marrow constitute the primary lymphoid organs involved in the production and early clonal selection of lymphocyte tissues.ne of the main functions of the lymph system is to provide an accessory return route to the blood for the surplus three litres. The other main function is that of defense in the immune system. Lymph is very similar to blood plasma: it contains lymphocytes and other white blood cells.

Alone we are rare. Together we are strong.â¥ Donate Today The lymph system (also known as the lymphatic system) is composed mainly of lymphoid tissue, lymph vessels, and a clear fluid called lymph.

- The components of the lymphatic system are divided into two groups – the primary organs and the secondary organs. 1  Primary Organs: The thymus gland and the bone marrow are primary organs. They regulate the production and differentiation of lymphocytes – the cells that make up the immune system. Secondary Organs: The secondary organs include the lymphatic vessels, lymph nodes, aggregated lymphoid tissue, and spleen. These secondary organs are involved, to some extent, in all three lymphatic functions.
