anemia patho - Exam 1B Flashcards
abnormal anemia
sickle cell disease
decreased Hgb content

hypochromic/pale
decreased number of circulating erythrocytes
decreased production
increased destruction
blood loss
iron is essential for
normal hgb production
folate & B12 are necessary for
normal DNA synthesis of RBCs
in megaloblastic anemia, MCV is
increased
in iron def anemia, MCV is
decreased
