Aplastic anemia is a blood disorder in which the body’s bone marrow doesn’t produce enough new red blood cells, white blood cells, and platelets. Bone marrows are the soft tissue in the center of bones and that are responsible for making blood cells.
Your blood is composed of three general types of blood cells in a liquid called blood plasma.
- Red blood cells– They carry fresh oxygen to the body’s cells and take carbon dioxide away from cells (and to the lungs to be exhaled).
- White blood cells- They help fight infections and foreign invaders. Platelets are disk-shaped cell fragments that help form blood clots to stop bleeding.
These blood cells each have their own lifespan and die naturally, to be replaced by new blood cells formed in bone marrow. Without this replacement process, health issues involving the heart and lungs, bleeding, and infection can develop.
