tubuloglomerular feedback


Also found in: Acronyms, Wikipedia.

tubuloglomerular feedback

a blood flow control mechanism operating in the kidneys that limits changes in glomerular filtration rate.

tubuloglomerular feedback

a feedback mechanism in the juxtaglomerular apparatus of the kidney, so that changes in solute concentration at the macula densa link to control the glomerular filtration rate and help ensure a relatively constant delivery of solutes to the distal tubule.

A blood flow control mechanism operating in the kidneys that limits changes in glomerular filtration rate.

tubuloglomerular feedback

an essential ingredient of the juxtaglomerular theory of renal autoregulation; TGF is the proposed mechanisms whereby the glomerular flow rate is modified by changes in the tubular flow rate.
