Organs of the Immune System: The Spleen Organs of the Immune System: The Spleen. Among organs that contribute to our immune response, there are two categories: primary lymphoid organs and secondary lymphoid organs. The spleen is a secondary lymphoid organ. Your spleen is found about halfway up your torso in the left abdominal cavity.

Spleen The spleen is a center of activity of the mononuclear phagocyte system and can be considered analogous to a large lymph node, as its absence causes a predisposition to certain infections. In humans, the spleen is brownish in color and is located in the left upper quadrant of the abdomen.

Lymphatic System Components 1 The spleen is the largest organ of the lymphatic system. 2  Its primary function is to filter blood of damaged cells, cellular debris, and pathogens. 3  Like the thymus, the spleen houses and aids in the maturation of lymphocytes. 4  Lymphocytes destroy pathogens and dead cells in the blood.he lymphatic system plays a vital role in the proper functioning of the body. One of the major roles of this organ system is to drain excess fluid surrounding tissues and organs and return it to the blood. Returning lymph to the blood helps to maintain normal blood volume and pressure.

Lymphoid: Primary and Secondary Lymphoid Tissues Secondary lymphoid tissues are arranged as a series of filters monitoring the contents of the extracellular fluids, i.e. lymph, tissue fluid and blood. The lymphoid tissue filtering each of these fluids is arranged in different ways.

Spleen The spleen is a brown, flat, oval-shaped lymphatic organ that filters and stores blood to protect the body from infections and blood loss. Protected by our ribs, the spleen is located between the stomach and the diaphragm in the left hypochondriac region of the abdominal body cavity. The splenic artery branches off from the aorta and the celiac trunk to deliver oxygenated blood to the spleen, while the splenic vein carries deoxygenated blood away from the spleen...

Lymphoid: Primary and Secondary Lymphoid Tissues They provide an environment for stem cells to divide and mature into B-and T-cells: There are two primary lymphatic organs: the red bone marrow and the thymus gland. The development of white blood cells (haemopoesis) was covered briefly in the section on blood. Both T-cell and B-cells are 'born' in the bone marrow.

Spleen The spleen is a lymphatic organ that performs the valuable function of filtering blood. While it is an important organ, it can be removed when necessary without causing death. This is the case because other organs, such as the liver and bone marrow, can perform filtration functions in the body.ike the thymus, the spleen houses and aids in the maturation of immune system cells called lymphocytes. Lymphocytes are white blood cells that protect against foreign organisms that have managed to infect body cells.

- Lymphoid Organs. 1  Central - (primary) Lymphocytes develop from precursor cells in bone marrow and thymus. 2  Peripheral - (secondary) Lymphocytes respond to antigen lymph nodes or spleen.

Overview of the Spleen The splenic artery brings blood to the spleen from the heart. Blood leaves the spleen through the splenic vein, which drains into a larger vein (the portal vein) that carries the blood to the liver. The spleen has a covering of fibrous tissue (the splenic capsule) that supports its blood vessels and lymphatic vessels.

The spleen and its role in immune function Essentially, the spleen is a storage container and filter for blood, though it is part of the lymphatic system. In fact, it’s the largest lymph node in the body. One of its tasks is to remove harmful bacteria and viruses in the blood stream.

The Spleen The spleen is found on the left side of your body, behind the stomach on a level with the 9th to 11th ribs. It is similar in structure to a lymph node, and is the largest lymphatic organ in the body. The spleen contains two main types of tissue-white pulp and red pulp.his leaflet gives a brief overview of the spleen and its functions. The spleen is an organ about the size of a clenched fist found on the left-hand side of your upper abdomen. Its main functions are to filter your blood, create new blood cells and store platelets.

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.

Development of peripheral lymphoid organs and natural killer cells depends on the helixâloopâhelix inhibitor Id2 However, their splenic architecture is normal, exhibiting T-cell and B-cell compartments and distinct germinal centres. The cell population that produces lymphotoxins, essential factors for the development of secondary lymphoid organs, is barely detectable in the Id2-/- intestine. Furthermore, the null mutants show a greatly reduced population of natural killer (NK) cells, which is due to an intrinsic defect in NK-cell precursors.

Enlarged Spleen (Splenomegaly) 1 It also is part of the lymphatic system and produces lymphocytes, a type of white blood cell that are a part of the immune system that helps to prevent and fight infection.  The spleen also acts as a reservoir for red blood cells and platelets, should the body need them.

Medical Terminology for Cancer Spleen. The spleen is an organ in the upper left abdomen, which filters blood, disposes of worn-out red blood cells, and provides a 'reserve supply' of blood. It contains both red tissue, and white lymphatic tissue. Different parts of the the spleen specialize in different kinds of immune cells. Lymphocytes initially develop in the bone marrow. 2  Some migrate to the thymus, where they mature into T cells; others mature in the bone marrow as B cells. 3  Neutrophils: are the most abundant type of white blood cells and are an important part of the innate immune system.

- It is positioned in the left upper abdomen, and is the largest organ of the lymphatic system. The spleen serves a critical role in immune function because it purifies the blood and helps the immune system to recognize and attack foreign pathogens and allergens. The spleen is composed of the red pulp and white pulp. The white pulp produces and grows immune cells as well as blood cells. On the other hand, the red pulp is responsible for purifying the blood and removing dead or old blood cells.

Immune Organs - organs of the immune system The lymphatic system consists of two parts, the primary and secondary organs. The thymus gland (located beneath the breast bone, and functioning at its peak during adolescence) and the bone marrow produce specialized lymphocytes—T-cells and B-cells and dispatching them through the lymph vessels to the secondary organs.o, the bone marrow creates the stem cells which become the cells of the immune system. Lymphocytes are sent from the bone marrow to the thymus gland to mature and are then stored in the secondary organs of the lymph system and in the blood stream.

Medical Terminology Cardiovascular, Immune, Lymphatic Systems, & Blood one of the primary lymphatic organs, it is located anterior to the ascending aorta and posterior to the sternum between the lungs. It plays an important role in the development of the body's immune system, particularly from infancy to puberty.
