Critmeter
WebIndeed, the kidney has been proposed to act as a “critmeter,” regulating hematocrit by adjusting RBCV and PV mediated by EPO (Donnelly, 2001). Also, increased PV after 2 weeks of ET coincides with elevated EPO while RBCV remains unaffected which supports that a reduced hematocrit due to a sole expansion in PV may regulate erythropoiesis ... WebJul 1, 2007 · Further, it is proposed that the kidney coordinates the relative volumes of these 2 blood components and in so doing regulates the hematocrit. This novel function as proposed is a functional concept whereby the kidney does not simply produce erythropoietin, but that the kidney regulates the hematocrit is termed the critmeter function.

WebThe 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 pressure required to trigger the production of erythropoietin. The balance of the ...
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. 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. By regulating red cell mass through erythropoietin and plasma volume through excretion of salt and water, the …
WebDec 13, 2024 · The "critmeter" theory suggests that O 2 sensors located within the juxtamedullary apparatus regulate the hematocrit via modulation of renal erythropoietin (EPO) production according to arterial O 2 content-dependent changes in tissue O 2 pressure. Hence, the initial decrease in hematocrit can be considered as a primary … WebOct 26, 2024 · A further interaction that arises from the critmeter theory is that the reduction in PV decreases glomerular filtration rate and thereby the O 2 consuming tubular sodium reabsorption (21, 23). The lower renal V̇ o 2 would then augment the increase in renal tissue P o 2 that arises from the restoration of C a O 2. In that manner, the critmeter ...
WebThe critmeter is proposed to be a functional unit located at the tip of the cortical labyrinth at the juxta-medullary region of the kidney where erythropoietin is made physiologically.
WebJul 1, 2014 · The likely answer is that the kidney is the body's “critmeter,” through its role in the synthesis and release of erythropoietin . Consequently, in order for the kidney to mount an appropriate response to anemia, through synthesis and release of erythropoietin, cortical tissue P o 2 must fall in response to anemia. ceiling fan knocking noiseWebJul 2, 2016 · Crits build up in the background with every hit you make, whether inside V.A.T.S., V.A.F.S., or neither.
