Answered Correct 2026 Edition.
Describe erythropoiesis and elements needed to promote effective RBC production. - Answer
** production of RBC's stimulated by erythropoietin (from kidneys) **
Protein (amino acid) Synthesis component of plasma membrane ↓ strength, elasticity, flexibility
of plasma membrane, hemolytic anemia
Intrinsic factor GI absorption of vit B12 Pernicious anemia
Cobalamin (vit B12) Synthesis of DNA and RNA, maturation of erythrocytes, facilitator, folate
metabolism Macrocytic (megaloblastic anemia)
Folate (folic acid) Synthesis of DNA & RNA, maturation of erythrocytes Macrocytic
(megaloblastic anemia)
Vit B6 (pyridoxine) Heme synthesis, possibly ↑folate metabolism Hypochromic-microcytic
anemia
Vit B2 (riboflavin) Oxidative reactions Normochromic-normocytic anemia
Vit C (ascorbic acid) Iron metabolism, acts as a reducing agent to maintain iron in its ferrous
form Normochromic-normocytic anemia
Pantothenic acid Heme synthesis Unknown in humans*
Niacin none, but needed for respiration in mature erythrocytes Unknown in humans
Vit E Synthesis of heme, possible protection against oxidative damage in mature erythrocytes
Hemolytic anemia with ↑ cell membrane fragility, shortens life span of erythrocytes with CF
, What are causes of anemic conditions? - Answer o Impaired erythrocyte production
o Acute or chronic blood loss
o Increased erythrocyte destruction
> caused by deformities or premature distruction <
o Combination of the above
Differentiate the various types of anemias - Answer Cytic = changes in size
> Macrocytic
> microcytic
> normocytic
Chromic = changes in hemoglobin content
> Normochromic
> hypochromic
Identify normal physiologic adaptations to anemia. - Answer > Movement of interstitial fluid
into plasma ("thins" the blood)
> Blood flow becomes turbulent, creates
hyperdynamic state, vessels dialate (due to hypoxemia), more peripheral blood flow/venous
return
> Increased heart rate (tachycardia), higher stroke vol, failure ensues due to "high output"
> Cardiomyopathy and heart valve insufficiency
> Respiratory rate increases, especially with activity
> Skin color changes, Pallor due to reduced hemoglobin, Loss of elasticity, graying of hair
> Renal changes, Aldosterone secretion (means more NaCL = more water)
