Question

__________ is an illustration of iron deficiency seen in individuals who have expanded their blood by increased activity?

1) Microcytic anemia
2) Athlete's anemia
3) Macrocytic anemia
4) Sickle cell anemia

Answer 1

Athlete's anemia is the term used to describe an expanded blood volume state in individuals after increased activity that appears like iron deficiency anemia; however, in true iron deficiency anemia, red blood cells are microcytic.

Step-by-step explanation:

An illustration of iron deficiency seen in individuals who have expanded their blood by increased activity is athlete’s anemia. Athlete's anemia occurs when physical activity leads to an expansion of plasma volume in the blood, which can dilute the concentration of red blood cells and mimic iron deficiency anemia. Despite the term, it's not a true anemia, but rather a temporary state that can be mistaken for one. In actual iron deficiency anemia, the red blood cells are typically microcytic, meaning that they are smaller than normal due to a lack of iron, which is necessary for the production of hemoglobin. This is in contrast to macrocytic anemia, where red blood cells are larger due to deficiencies in vitamin B12 or folate, or sickle cell anemia, a genetic disorder in which the cells are abnormally shaped and impair oxygen delivery.
