Alterations in hematologic function can occur in cell count or function, and can be caused by a variety of factors, including malnutrition, genetics, neoplastic, and autoimmune. The hematologic system produces new blood cells through a process called hematopoiesis, which occurs in bone marrow. The bone marrow contains multipotential stem cells that differentiate into four types of blood cells: Erythrocytes: The most common type of blood cell Granulocytes: A group of white blood cells that contain granules in their cytoplasm Agranulocytes: A type of white blood cell that includes monocytes and lymphocytes Platelets: Also called thrombocytes
Alterations of erythrocyte function can involve: Insufficient or excessive numbers of erythrocytes in the circulation Normal numbers of cells with abnormal components Anemia is a condition in which there are too few erythrocytes or an insufficient volume of erythrocytes in the blood. Other hematologic disorders include: Blood cell cancers, Genetic disorders, HIV related conditions, Sickle cell disease, and Complications due to chemotherapy treatment or transfusions.
