Bone Marrow role in immune system
White blood cells help the body fight against infection. There are many different types of white blood cells, which include: 1  Lymphocytes, neutrophils, and monocytes. 2  These white blood cells fight against invading bacteria, viruses, or fungi to help destroy infection.lood is made up of red blood cells, platelets, and different kinds of white blood cells. These cells are all suspended in liquid plasma. Our immune system protects the body from disease. It kills unwanted micro-organisms such as bacteria and viruses that may invade our bodies. Bone marrow is the spongy tissue inside our bones. All bones in newborn babies have active marrow, which means they are producing new marrow cells. By the time your child reaches young adulthood, the marrow inside the bones of the hands, feet, arms, and legs stop producing new marrow cells.In adults, active marrow is found inside the spine, hip and shoulder bones, ribs, breastbone, and skull.lood is made up of red blood cells, platelets, and different kinds of white blood cells. These cells are all suspended in liquid plasma. Our immune system protects the body from disease. It kills unwanted micro-organisms such as bacteria and viruses that may invade our bodies. The Job of the Bone Marrow. Bone marrow is where B-cells are selected, developed and matured in a process called hematopoiesis. Two types of stem cells are made in the bone marrow: stromal cells, which make fat, cartilage and bone, and hematopoietic stem cells, which make blood cells.he bone marrow is one of two primary lymphoid organs, along with the thymus. Bone marrow is a sponge-like tissue found at the center of the body's large, flat bones. Bone marrow plays an important role in the immune system as it produces and releases the white blood cells.ome of these white blood cells will develop the properties of mature white blood cells in the thymus, an organ found in front of the heart, which will enable these cells to identify and attack infectious cells such as bacteria and viruses. Our bone marrow produces blood cells, called red blood cells, platelets, and white blood cells. Inside the marrow, blood cells start off as young, immature cells called stem cells.lood is made up of red blood cells, platelets, and different kinds of white blood cells. These cells are all suspended in liquid plasma. Our immune system protects the body from disease. It kills unwanted micro-organisms such as bacteria and viruses that may invade our bodies. The bone marrow is the site of production of all blood cells, including white blood cells. White blood cells are what defend our bodies from infections.So, if the bone marrow does not work right, and white cells are not produced in adequate numbers or with normal function, the body becomes at risk for infection.he bone marrow is the site of production of all blood cells, including white blood cells. White blood cells are what defend our bodies from infections. Bone marrow produces and releases white blood cells. Bone marrow is found in the middle of longer bones in the body.Bone marrow is a soft spongy tissue which is able to produce red and white blood cells and platelets.ome of these white blood cells will develop the properties of mature white blood cells in the thymus, an organ found in front of the heart, which will enable these cells to identify and attack infectious cells such as bacteria and viruses. The bone marrow produces B cells, natural killer cells, granulocytes and immature thymocytes, in addition to red blood cells and platelets. Thymus -- The function of the thymus is to produce mature T cells. Immature thymocytes, also known as prothymocytes, leave the bone marrow and migrate into the thymus.endritic cells, which also originate in the bone marrow, function as antigen presenting cells (APC). In fact, the dendritic cells are more efficient apcs than macrophages. These cells are usually found in the structural compartment of the lymphoid organs such as the thymus, lymph nodes and spleen. Bone marrow is the flexible tissue in the interior of bones. In humans, red blood cells are produced by cores of bone marrow in the heads of long bones in a process known as hematopoiesis.On average, bone marrow constitutes 4% of the total body mass of humans; in an adult weighing 65 kilograms (143 lb), bone marrow typically accounts for approximately 2.6 kilograms (5.7 lb).n addition, the bone marrow contains hematopoietic stem cells, which give rise to the three classes of blood cells that are found in the circulation: white blood cells (leukocytes), red blood cells (erythrocytes), and platelets (thrombocytes). If the white blood cells being made in the bone marrow are abnormal, that is characteristic of leukemia. If the bone marrow isn't making red blood cells, it is called aplastic anemia.he bone marrow is one of two primary lymphoid organs, along with the thymus. Bone marrow is a sponge-like tissue found at the center of the body's large, flat bones.
