Vasodilation have positive effects on the afterload and blood pressure.
Vasodilation have positive effects on the afterload because afterload goes down when aortic pressure and systemic vascular resistance decreases through vasodilation.
Vasodilation is a mechanism which occurs in order to enhance blood flow to areas of the body that are lacking oxygen and nutrients. The vasodilation causes a decrease in systemic vascular resistance (SVR) and an increase in blood flow that results in reducing blood pressure.
