Quizplus · Accepted Answer

The kidneys release erythropoietin, a hormone that stimulates the production of red blood cells in the bone marrow, which in turn increases hemoglobin levels in the body. Iron is an essential component of hemoglobin, but it is not released by the kidneys. Oxygen is not a substance released by the kidneys, but rather it is carried by hemoglobin in red blood cells. Erythrocytes are red blood cells, but they are not released by the kidneys to increase hemoglobin levels.
