Term
| arteriole sphincters are made of: |
|
Definition
|
|
Term
| a sphincter contracts to decrease the arteriole diameter by 1/2. if all other variables stay the same, this will decrease blood: |
|
Definition
|
|
Term
| if the amplitude of the finger pulse signal indicates the amount of blood flowing through the finger, what is the effect of cooling on blood flow through the fingers? |
|
Definition
| cooling decreases peripheral blood flow |
|
|
Term
| blood fow can be controlled by 'sphincters', which are bands of smooth muscles around arterioles. what is the effect of cooling on these smooth muscles? |
|
Definition
| cooling makes these smooth muscle sphincter contract |
|

Term
| when the ice bag is left on the wrist, the peripheral blood flow: |
|
Definition
|
|
Term
| what happens to blood flow through the finger pulse when the ice bag is removed? |
|
Definition
| blood flow quickly increases |
|
|
Term
| what is the effect of removing the ice bag on the arteriole sphincters? |
|
Definition
| smooth muscle sphincter relax |
|
|
Term
| a sphincter contracts to decrease the arteriole diameter (or radius) to 1/2. if all of the other variables stay the same, this will: |
|
Definition
| decrease blood flow to 1/16 |
