Different types of leukemia are formed from different cells. To understand the different types of leukemia, it helps to know something about the blood and lymph systems.
Bone marrow is the soft inner part of some bones such as the skull, shoulder blades, ribs, pelvis, and backbones. Bone marrow Bone marrow matures made up of a small number of blood stem cells, more mature blood-forming cells, fat cells, and supporting tissues that help cells grow. Inside the bone marrow, blood stem cells develop into new blood cells. During this process, the cells become either lymphocytes a kind of white blood cell or other blood-forming cells.
These blood-forming cells can develop red blood cells, white blood cells other than lymphocytesor platelets. Red blood cells carry oxygen from the lungs to all other tissues in the body, and take carbon dioxide back to the lungs to be removed. Having too few red blood cells in the body anemia can make you feel tired, weak, and short of breath because your body tissues are not getting enough oxygen.
Platelets are cell fragments made by a type of bone marrow cell called the Bone marrow matures.
Platelets are important in plugging up holes in blood vessels caused by cuts or bruises. Having too few platelets thrombocytopenia may cause you to bleed or bruise easily. White blood cells help the body fight infections.
Having too few white blood cells neutropenia lowers your immune system and can make you more likely to get an infection. Lymphocytes are mature, infection-fighting cells that develop from lymphoblastsa type of blood stem cell in the bone marrow.
Lymphocytes are the main cells that make up lymphoid tissue, a major part of the immune system. Lymphoid tissue is found in lymph nodesthe thymus gland, the spleen, the tonsils, the adenoids, and is scattered throughout the digestive and respiratory systems and the bone marrow.
The 2 major types of lymphocytes are B lymphocytes B cells and T lymphocytes T cells. Lymphocytes help protect your body from germs. Some types of lymphocytes help regulate the immune system.
