Narrower |
The _____ (more constructed) a vessel is the greater the resistance |
|
|
Inverse relationship |
A relationship between 2 variables; on increases other decreases and vice versa |
|
|
Increased resistance; decrease in flow Decreased resistance; increase in flow |
What is the relationship between R and flow? |
|
|
Flow is inversely proportional to resistance |
Explain the equation f=1/R |
|
|
The longer the vessel the greater the friction and resistance will be, the lower the rate of flow through that vessel. |
What is the relationship between vessel length and resistance? Length and flow? |
|
|
Turbulence increase resistance Turbulence decrease flow |
What is the relationship between turbulence and resistance? Turbulence and flow? |
|
|
-high flow rates -irregular surfaces -sudden changes in vessel diameter upset the smooth flow of blood |
What are the three factors that increase turbulence in the blood stream? |
