Other lymphocytes begin life in red bone marrow and become fully formed in the lymphatic tissues, including the thymus, spleen, and lymph nodes. It may also develop as a side effect of cancer treatment. Theres also a synthetic (man-made) form of erythropoietin that healthcare providers use to treat anemia that results from chronic kidney disease. They respond to various allergens that cause the release of histamines, heparin, and other substances. These cells are so-called because they mature in the thymus, which is a small organ in the upper chest, just behind the sternum. This may be due to chronic smoking or living in a high-altitude environment where air oxygen levels are lower. Together with the liver and spleen, red bone marrow also plays a role in getting rid of old red blood cells. T cells help B cells make antibodies against invading bacteria, viruses, or other microbes. It becomes active about 3 weeks later. Bone marrow is obtainable for examination by bone marrow biopsy and bone marrow aspiration. It contains platelets, red blood cells, and stem cells to produce white blood cells.) Some new cells remain as stem cells, while others go through a series of maturing stages, as precursor or blast cells, before becoming formed, or mature, blood cells. Past studies suggest that people aged over 50 years have a higher risk of complications following bone marrow transplantation. People with Lyme disease, malaria, or recent tattoos or piercings should wait at least a year before donating bone marrow. The circulatory system touches every organ and system in the body.
