To list: The three paracrine molecules that leads to vasodilation along with their source.
Introduction: The smooth muscles present in blood vessels are known as vascular smooth muscles. These muscles are arranged in a circular or spiral manner inside the vessels. The narrowing of the lumen of vessels is termed as vasoconstriction. On the contrary, widening of lumen of vessels is termed as vasodilation.
To determine: The two ways except for paracrine signals which mediate the smooth muscle contraction in arterioles.
Introduction: Vasoconstriction decreases the amount of blood, which flows to a particular part of the body, whereas vasodilation increases the amount of blood which flows. On the contrary, the pressure of blood increases in vasoconstriction and decreases in vasodilation.
