WebEDITOR’S SUMMARY. Hemodilution is the practice of intentionally removing red blood cells to lower the hematocrit. This has the obvious result that the red cells can be replaced later if needed. However, the practice was first used to improve circulatory hemodynamics: lowered viscosity can increase the venous return to the heart and thereby raise cardiac output. WebIt is unclear what causes the increase in red blood cells with exercise. Erythrocytes are produced in bone marrow in response to erythropoietin, a hormone released by the kidney. Erythropoietin is secreted when low oxygen levels are low. However, exercise doesn't usually cause oxygen levels to drop low enough for that to occur.
