What determines autoregulation of blood flow to the heart?
|
Local metabolites, dilation of the coronary arteries
|
|
What unique effect do the autoregulation factors have in the lungs, and why does this occur?
|
Hypoxia causes vasoconstriction
Occurs so that blood is shunted ONLY to the highly oxygenated areas |
