How would the process of red blood cell production be affected by constricting the arteries that supply blood to the kidney? Explain your answer. Name three other situations that would similarly affect the process of red blood cell production.
What will be an ideal response?
Red blood cell production would be increased. Constricting arteries would reduce blood flow; thus, the kidney would experience hypoxia. The kidney produces the hormone erythropoietin, which stimulates red blood cell production, in response to hypoxia. Increased red blood cell production would also result from anemia, extended presence at high altitude, and following hemorrhage.
