Blood Disorders

Sickle Cell Anemia, Symptoms, Pathophysiology 

Hematocrit, Anemia, Polycythemia

 Intrinsic factor is essential for the absorption of vitamin B12. Pernicious anemia will develop when a lack of intrinsic factor leads to a B12 deficiency. Aplastic anemia results from damage to or inhibition of the red bone marrow. Sickle-cell anemia is caused by defective hemoglobin. A person who has suffered excessive blood loss would exhibit hemorrhagic anemia. 

 A patient who lacks intrinsic factor would likely develop __________. 

Red Blood Cell Life Cycle and Disorders

 Sickling of RBCs infected with malaria reduces the parasites’ ability to survive and enhances macrophages’ ability to destroy the infected RBCs and the parasites they contain. 

 Individuals with malaria have a better chance of surviving the infection if they have which type of anemia?

 Leukopenia is an abnormally low number of white blood cells. In contrast, leukocytosis is characterized by an increase in white blood cell numbers as a normal response to infection. Leukopoiesis is the production of white blood cells. Polycythemia is an abnormally high number of erythrocytes.  

 Overproduction of white blood cells is called __________. 

Iron Deficiency Anemia, Pathophysiology, Symptoms, Treatment

 Aplastic anemia results from the destruction or inhibition of the red marrow by drugs, chemicals, ionizing radiation, or viruses. 

 Which type of anemia results from the destruction or inhibition of the red marrow by drugs, chemicals, ionizing radiation, or viruses? 

 rupture of red blood cells caused by parasites 

Pernicious anemia is caused either by absence of vitamin B12 in the diet or by a deficiency of intrinsic factor (necessary to absorb vitamin B12).

the lack of vitamin B12 in the diet or a deficiency of the intrinsic factor needed to absorb vitamin B12

 the absence or depressed synthesis of globin chains 

 abnormal production of hemoglobin caused by genetic defect
