The four most important normal functions of the spleen are as follows: Clearance of microorganisms and particulate antigens from the blood stream. Synthesis of immunoglobulin G (IgG), properdin. A number of specialised tissues are important for the proper functioning of the immune system. Among these are the lymph nodes, which provide an ideal environment for communication between immune cells. This environment is necessary for proper activation of the T and B cells (or lymphocytes) that are required for defence against many pathogens The role of the spleen in the induction of an immune response to orally administered antigens is still under discussion. Although it is well known that after oral antigen administration specific germinal centres are not only formed in the Peyers patches (PP) and the mesenteric lymph nodes (mLN) but also in the spleen, there is still a lack of functional data showing a direct involvement of.

The immune response mainly involves the lymphatic system. The lymphatic system is a major part of the immune system. It produces leukocytes called lymphocytes. Lymphocytes are the key cells involved in the immune response. They recognize and help destroy particular pathogens in body fluids and cells It acts revitalizing the adrenal glands at the cellular level, improving its functionality and reducing the risk of degenerative diseases. Depending on the oxidative stress intensity the immune system is progressively affected, opening the doors to infections and degenerative diseases Leucocytes, also known as white blood cells, are immune cells that circulate within the blood and lymphatic system. There are 5 main types: neutrophils, monocytes, eosinophils, basophils and lymphocytes. We will begin with a basic overview of these general types, followed by more detailed articles considering their production, role and subtypes activating other parts of your immune system. Your spleen also removes old and misshapen red blood cells and platelets from your bloodstream. It stores a small supply of healthy red blood cells and platelets for your body to use in an emergency. If your bone marrow isn't working as it should, your spleen can also be a back-up site for making. The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. White blood cells, also called leukocytes (say: LOO-kuh-sytes), are part of this defense system. There are two basic types of these germ-fighting cells: phagocytes (say: FAH-guh-sytes), which chew up invading germs

When we talk about the immune system, we are actually talking about a complicated network of organs and cells. Several organs and cells make up the immune system, including your lymph nodes, spleen, bone marrow, lymphocytes (white blood cells known as B- and T-cells), the thymus, and leukocytes (another type of white blood cell) Thymus definition is - a glandular structure of largely lymphoid tissue that functions especially in cell-mediated immunity by being the site where T cells develop, is present in the young of most vertebrates typically in the upper anterior chest or at the base of the neck, and gradually decreases in size and activity after puberty
