Brain blood flow autoregulation?
Yes..
What is ventilation perfusion coupling?
Ventilation perfusion coupling is the amount of gas reaching alveoli & blood flow in pulmonary capillaries; local autoregulation.
The ability of a tissue to automatically adjust its blood flow to match its metabolic demand is?
autoregulation
What is autoregulation?
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.
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
IS the adjustment of blood flow to each tissue in proportion to its requirements at any point in time termed autoregulation?
Yes.
What is a local decrease in blood flow?
titty sprinkles
How is coronary blood flow regulated?
Coronary blood flow is regulated by local metabolic factors. Adenosine, nitric oxide, and decreased oxygen all act as vasodilators which improve blood flow in coronary circulation.
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
What is the blood flow in the body?
The flow or blood
What is blood flow resistance?
The resistance of blood flow is what?
What is blood flow generated by?
The flow of blood times the resistance of the blood vessels.
