Where does hematopoiesis take place, producing new RBCs?

• red bone marrow

• yellow bone marrow

• synovial membrane

• articular cartilage

Figure 1 is a proposed model of the feedback system controlling erythrocyte (red blood cell) production. Air is less dense at very high elevations, so less oxygen is available than in the denser air at sea level. Based on the model in Figure 1, if a person travels from sea level to a high elevation location, which of the following correctly predicts the response to the decreased blood oxygen level?

• More erythropoietin will be secreted from the kidneys, decreasing production of erythrocytes.

• More erythropoietin will be secreted from the kidneys, increasing production of erythrocytes.

• Less erythropoietin will be secreted from the kidneys, decreasing production of erythrocytes.

• Less erythropoietin will be secreted from the kidneys, increasing production of erythrocytes.
