To what might some cases of anemia, which causes red blood cell production to increase in response to iron deficiency or blood loss, lead?
| a. |
a parasitic infection |
|
| b. |
expansion and porosity of long bones |
|
| c. |
cribra orbitalia in eye orbits |
|
| d. |
a genetic disease |
Iron deficiency anemia or anemia due to blood loss results in porotic lesions on the orbital roof , a condition known as cribra orbitalia. Here the bone becomes spongy and porous.
The orbit lies in the skull and is the cavity that holds the eye and its contents.
When the iron deficiency anemia appears in a person his blood will start producing more red blood cells.
Another view is that reduction in iron in blood helps to defend pathogens. This results in the bone tissue becoming soft and spongy which can be considered as a biological attempt to keep away pathogens than being a result of malnutrition.

A student asks the nurse about the causes of anemia secondary to destructive/loss of red blood cells. The nurse will respond to the student by stating these types of anemias may be due to: Peptic ulcer disease Chronic kidney disease Fibrosis in the bone marrow Folic acid deficiency***
Sickle cell anemia is a genetic disorder that causes red blood cells to take on an abnormal, crescent shape. This inherited disorder is the result of a single base change from A to T. This changes the amino acid glutamic acid to valine at position six of the hemoglobin protein. Based on this information, sickle cell anemia results from a(n) ________ mutation. substitution mutation deletion mutation insertion mutation silent mutation
