Does angiotensin have different constrictor effects compared to noradrenaline on resistance and capacitance vessels in cats?
This preclinical study demonstrates that angiotensin primarily acts on precapillary resistance vessels, while noradrenaline acts on both arterial and venous sides of the circulation.
Folkow et al. (1961) studied this question.
