Autoregulation is a specific form of homeostasis used to describe the tendency of the body to keep blood flow constant when blood pressure varies.[1]. While most systems of the body show some degree of autoregulation, it is most clearly observed in the kidney, the heart, and the brain.[2] Perfusion of these organs (especially the latter two) is essential for life, and through autoregulation the body can divert blood (and thus, oxygen) where it is most needed. One key component of autoregulation is the absence of central control. The "auto" in autoregulation refers to the ability of the organ to maintain a stable flow without the involvement of the autonomic nervous system.

What is an example of autoregulation?
I'm also looking for an example of autoregulation. I think one is about muscles releasing oxygen when there is low level of it e.g after heavy excercise
IS the adjustment of blood flow to each tissue in proportion to its requirements at any point in time termed autoregulation?
Yes.
Myogenic mechanism of renal autoregulation?
The myogenic mechanism occurs whenstretching triggers contraction of smooth muscles in the wall of arterioles to normalize blood flow and GFR (glomerular filtration rate) by increasing or decreasing blood pressure. N.B. i rephrased the concept a little bit.source: principle of A&P by Tortora & Derrickson
Brain blood flow autoregulation?
Yes..

What stimulus in local autoregulation of blood flow?
nitric oxide
How the kidney protects itself from elevated hydrostatic?
Renal Autoregulation.
During exercise blood flow to the active skeletal muscles in increased by autoregulation propose a mechanism based on the need for nutrients that would explain how an autoregulation might take place?
vasodilation
The ability of a tissue to automatically adjust its blood flow to match its metabolic demand is?
autoregulation
IS the adjustment of blood flow to each tissue in proportion to its requirements at any point in time termed autoregulation?
Yes.
What process assures that minor changes in blood pressure do not affect the kidneys filtration rate?
Autoregulation. You're welcome :)
What has the author Linda Marie Facchini written?
Linda Marie Facchini has written: 'Characterisation of the Myc negative autoregulation mechanism'
What is ventilation perfusion coupling?
Ventilation perfusion coupling is the amount of gas reaching alveoli & blood flow in pulmonary capillaries; local autoregulation.

What distinguishes autoregulation from extrinsic regulation?
Auto regulation (intrinsic) is when a cell, organ, or organ system automatically adjusts itself in response to a change in the environment. Extrinsic regulation involves the nervous and/or endocrine system detecting a change and sending a signal or releasing a chemical to facilitate change in another organ system, organ, or cell.
