Question

Quizplus · Accepted Answer

Anemia is a condition in which the number of red blood cells or hemoglobin concentration is reduced below the normal values for age.This results in a decreased oxygen-carrying capacity of blood.Increased blood viscosity is usually a function of too many cells or of dehydration,not of anemia.A depressed hematopoietic system or abnormal hemoglobin can contribute to anemia,but the definition depends on the decreased oxygen-carrying capacity of the blood.
