Quick Summary

Erythropoiesis is the biological process of producing red blood cells, also known as erythrocytes. This vital process occurs primarily in the bone marrow of adults. Red blood cells are crucial for transporting oxygen from the lungs to the body's tissues and carrying carbon dioxide back to the lungs for exhalation.123

The production of red blood cells is regulated by the hormone erythropoietin, which is mainly produced by the kidneys. When the body needs more red blood cells, such as after blood loss or in low-oxygen environments, erythropoietin levels increase, stimulating the bone marrow to accelerate production. This ensures a constant supply of oxygen-carrying cells to meet the body's demands.43
