Question

question 5 of 10
the production of red blood cells is stimulated by which of the following conditions?
kidney failure
a low iron diet
low blood oxygen level
polycythemia

Explanation:

When blood oxygen levels are low, the kidneys secrete erythropoietin, a hormone that stimulates the bone - marrow to produce more red blood cells. Kidney failure impairs erythropoietin production and thus reduces red - blood - cell production. A low iron diet can lead to iron - deficiency anemia and decreased red - blood - cell production. Polycythemia is a condition of excessive red - blood - cell production, not a stimulant for it.

Answer:

C. Low blood oxygen level
