in arterioles the pressure depends on the impedance of the vessel(elasticity and youngs modulus) cardiac output pre arteriolar resistance what i want to ask is will the pressure also depend on law of laplace for eg. if a there is peripheral vasodilation( the muscles of the artery wall are relaxed) so the tension is less the radius is high and hence using the equation( pressure=2*tension/r) the pressure in the arteriole is low is this arguememt valid??
