1
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?
A)Cooling increase peripheral blood flow.
B)Cooling does not change peripheral blood flow.
C)Cooling decrease peripheral blood flow.
2
Blood flow can be controlled by ‘sphincters’, which are bands of smooth muscles around arterioles. What is the effect of cooling on these smooth muscles?
A)Cooling makes these smooth muscle sphincters relax.
B)Cooling has no effect on the integrity of the smooth muscle sphincters.
C)Cooling makes these smooth muscle sphincters contract.
3

A)increases slowly.
B)remains at the same low level.
C)decreases slowly.
4
What happens to blood flow through the finger pulse when the ice bag is removed?
A)Blood flow quickly increases.
B)Blood flow does not change
C)Blood flow decreases.
5
What is the effect of removing the ice bag on the arteriole sphincters?
A)The smooth muscle sphincters contract.
