Verified step by step guidance

Understand the role of erythropoietin: Erythropoietin is a cytokine that plays a crucial role in the production of red blood cells by promoting the growth and differentiation of erythroid progenitor cells in the bone marrow.

Identify the site of production: Erythropoietin is primarily produced in the kidneys. This is a key point to remember as it helps regulate red blood cell production in response to oxygen levels in the blood.

Determine the site of action: Once produced, erythropoietin is released into the bloodstream and acts on the bone marrow to stimulate the production of red blood cells.

Review the options given: The problem provides several options for the sites of production and action of erythropoietin. Compare these options with the known biological roles and pathways of erythropoietin.

Select the correct answer: Based on the understanding that erythropoietin is produced in the kidneys and acts on the bone marrow, choose the option that correctly matches this information.
