Hematologic Disorders and Anemia Q 14

Which of the following blood components is decreased in anemia?
     A. Erythrocytes
     B. Granulocytes
     C. Leukocytes
     D. Platelets

Correct Answer: A. Erythrocytes

Anemia is defined as a decreased number of erythrocytes (red blood cells). RBC are produced in the bone marrow and released into circulation. Approximately 1% of RBC are removed from circulation per day. Imbalance in production to removal or destruction of RBC leads to anemia.

Option B: Granulocytopenia is a decreased number of granulocytes (a type of white blood cells). Granulocytopenia is a marked decrease in the number of granulocytes. Granulocytes are a type of white blood cell filled with microscopic granules that are little sacs containing enzymes that digest microorganisms. Granulocytes are part of the innate, somewhat non specific infection-fighting immune system.
Option C: Leukopenia is a decreased number of leukocytes (white blood cells). Leukopenia is a condition where a person has a reduced number of white blood cells. This increases their risk of infections. A person’s blood is made up of many different types of blood cells. White blood cells, also known as leukocytes, help to fight off infection. Leukocytes are a vital part of the immune system.
Option D: Thrombocytopenia is a decreased number of platelets. Thrombocytopenia is a condition in which there is a low blood platelet count. Platelets (thrombocytes) are colorless blood cells that help blood clot. Platelets stop bleeding by clumping and forming plugs in blood vessel injuries.
