In the negative feedback loop that controls the rate of eryt

In the negative feedback loop that controls the rate of erythropoiesis, the stressor (stimulus) is: a change in the normal percentages of each type of formed element. increased levels of carbon dioxide in the red bone marrow. increased levels of carbon dioxide in the cerebrospinal fluid decreased levels of oxygen in the kidney. decreased solute concentration of blood circulating in the hypothalamus.

Solution

D) Decreased levels of Oxygen in blood which is detected by kidney is the basic stimulus for erythropoiesis process. Low oxygen levels do not directly stimulate the erythropoiesis. Instead, it stimulates the kidneys to secrete the erythropoietin into the blood, and this hormone stimulates the bone marrow to produce erythrocytes(RBCs)
