Cardiovascular Regulatory Mechanism
Local Regulatory mechanism
The ability of the tissue to regulate their own blood flow
at specific area of body
BMT
intrinsic capacity to
compensate (give) for the changes in vascular resistance
to maintain blood flow
regulated by sympathetic constrictor nerve
by vasoconstriction/ vasodilation
Sympathetic system
Sympathetic
vasoconstrictor
system
Noradrenergic fibers
release NE to
alpha 1 and 2 receptor
Sympathetic and Parasympathetic
vasodilator
system
Cholinergic fibre
release
Ach
to
muscarinic receptor
Centre in medulla oblongata
Respiratory centre
Control the depth and rate of breathing
Vasomotor centre
Control diameter of blood vessel
Cardiac centre
regulate the rate and force of heart beat
Vasomotor tone
Continuous discharge of impulse through sympathetic (vasoconstrictor) fibre
OR the end result of a complex set of interactions that control relaxation and contraction of blood vessels
to r
egulate the pressure
by
producing constant partial state of constriction
of blood vessel
also known as
sympathetic vasoconstrictor tone
