5 Questions
What is the primary mechanism of acute blood flow control?
Rapid local vasodilation or vasoconstriction
Which theory proposes that tissue metabolism influences local blood flow by affecting oxygen availability?
Oxygen Lack Theory
What distinguishes long-term control of blood flow from acute control?
Physical sizes and numbers of blood vessels
How do long-term changes in blood vessel sizes and numbers contribute to better control of blood flow?
By adjusting flow proportionally to tissue needs
Which component plays a vital role in achieving rapid maintenance of appropriate local tissue blood flow during acute control?
Metarterioles
Learn about the mechanisms of local blood flow control, including acute control through rapid vasodilation or vasoconstriction, and the effects of tissue metabolism on blood flow. Explore theories such as the vasodilator theory and oxygen/nutrient lack theory.
