Erythrocyte Disorders Anemia is a condition in which the blood has an abnormally low oxygen- carrying capacity. Common causes of anemia include: at 1) an insufficient number of red blood cells 2) decreased hemoglobin content 3) abnormal hemoglobin Two such examples are Thalassemias and Sickle-cell anemia, which are caused by genetic defects.

F Thrombus is a clot that attaches to the wall of blood vessel. Embolus is a clot that comes off the wall of blood vessel and travel in the blood stream. accaned ablooking Embolism is the blockage of blood flow by an IgEembolus that lodges in a small blood vessel. Infarction refers to cell death that results from embolism.
