Critmeter
WebJul 29, 2024 · The focus on hemoglobin concentration as a target of natural selection for the last 2 decades has overlooked the regulatory role of the kidney as the “critmeter” . Here, hematocrit is regulated through the control of erythropoiesis and water retention and secretion via a feedback loop based on renal tissue oxygen pressure. WebI hypothesize that the critmeter is a functional unit that regulates the hematocrit. The critmeter is found at the tip of the juxtamedullary region of the cortical labyrinth in the kidney, where erythropoietin is made physiologically. Renal vasculature and nephron segment heterogeneity in sodium reabsorption generate the marginal tissue oxygen ...

WebAug 1, 2001 · Erythropoietin is distinct among the hematopoietic growth factors because it is produced primarily in the kidneys rather than the bone marrow. The kidney functions as a critmeter in that it senses oxygen tension and extracellular volume.
