Human Physiology/The Immune System specific pathogens that are causing disease (B cells produce antibodies against bacteria or viruses in the extracellular. fluid, while T cells kill cells that have become infected). The immune system is closely tied to the lymphatic system, with B and T lymphocytes being found primarily within lymph nodes. Tonsils and the thymus gland are also. considered lymph organs and are involved in immunity. We often don't realize how effective the immune system is. until it fails or malfunctions, such as when the lymphocytes are attacked by HIV in an AIDS patient.

Immune and Lymphatic Systems The immune and lymphatic systems are two closely related organ systems that share several organs and physiological functions. The immune system is our body’s defense system against infectious pathogenic viruses, bacteria, and fungi as well as parasitic animals and protists.he immune and lymphatic systems of the lower torso provides many vital functions to the body, including protection of the body from pathogens and the filtration and transportation of lymph, blood, and lipids. Many different structures, from red bone marrow in bones to the spleen, contribute to these processes.

- The spleen (from Greek σπλήν — splḗn) is an organ found in virtually all vertebrates. Similar in structure to a large lymph node, it acts primarily as a blood filter. The spleen plays important roles in regard to red blood cells (also referred to as erythrocytes) and the immune system.It removes old red blood cells and holds a reserve of blood, which can be valuable in case of hemorrhagic shock, and also recycles iron.he 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.

Immune System Lymph nodes are part of the immune system. They release lymphocytes, a certain type of white blood cell that fights infection. The blood vessels and lymph vessels carry the lymphocytes to and from different areas in the body. Each lymphoid organ plays a role in the production and activation of lymphocytes. Organs in the lymph system include: Adenoids.

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.he 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. Lymphoid tissues contain lymphocytes, and also contain other types of cells for support.

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.

LYMPHATIC SYSTEM AND IMMUNITY. The 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.he immune system is the major component of this defense. Lymphocytes, monocytes, lymph organs, and lymph vessels make up the system. The immune system is able to distinguish self from non-self. Antigens are chemicals on the surface of a cell.

Immune Organs - organs of the immune system In t the literature we find two groups of immune organs (or lymphoid organs as it is also part of the lymphoid System): Primary organs” - These are immune organs concerned with production and maturation of lymphoid cells and including bone marrow and thymus gland.“Secondary organs” - these immune organs are spots or sites in which the lymphocytes localize, identify unfamiliar antigens and triggers reaction in opposition to it.It Contains tonsils, lymph nodes, Spleen, Peyer’s patches (in the small intestines), appendix and liver.alking about the immune organs (i'll get back to the immune system cells later): Primary Organs: Thymus-located beneath the breast bone. Those two lobes! It functions at its peak during adolescence producing specialized lymphocytes-T-cells and B-cells and dispatching them through lymph vessels to secondary organs.

Immune System - Organs Of The Immune System lymphocytes bone lymph nodes. The organs of the immune system either make the cells that participate in the immune response or act as sites for immune function.These organs include the lymphatic vessels, lymph nodes, tonsils, thymus, Peyer's patch, and spleen.The lymph nodes are small aggregations of tissues interspersed throughout the lymphatic system. White blood cells (lymphocytes) that function in the immune response are concentrated in the lymph nodes.Lymphatic fluid circulates through the lymph nodes via the lymphatic vessels. As the lymph filters through the lymph nodes, foreign cells of microorganisms are detected and overpowered.he lymph nodes are small aggregations of tissues interspersed throughout the lymphatic system.

Organs of the Immune System: Your Shield Against Diseases The main organs in the immune system are the bone marrow, thymus, spleen and lymph nodes. Let us have a look at these immune system organs and functions. Bone Marrow: All the cells of the human immune system are formed in the bone marrow, found within the bones, by a process called hematopoiesis.-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.

- The lymphatic system plays a large role in immunity. This important system also absorbs digested fats from the small intestine. The components of the lymphatic system are divided into two groups – the primary organs and the secondary organs. 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.

Immune system The immune system is involved in many aspects of physiological regulation in the body. The immune system interacts intimately with other systems, such as the endocrine and the nervous systems. The immune system also plays a crucial role in embryogenesis (development of the embryo), as well as in tissue repair and regeneration.
