- a direct response of smooth muscle to
|
|
|
maintain
normal blood flow. In response to increasing
|
|
|
pressure
the small arteries and arterioles vasoconstrict,
|
|
|
thus
maintaining constant blood flow despite the
|
|
|
increase in
pressure.

|
|

- a response through a local neural circuit
|
|
|
which
controls blood supply in response to oxygen,
