Explanation: 

Detailed explanation-1: -Vasodilation: leads to greater blood flow to the area of inflammation, resulting in redness and heat. Vascular permeability: endothelial cells become “leaky” from either direct endothelial cell injury or via chemical mediators.

Detailed explanation-2: -The purpose of vasodilation is to increase blood flow to the tissues in the body. In response to a need for oxygen or nutrients, tissues can release endogenous vasodilators. The result is a decrease in vascular resistance and an increase in capillary perfusion.
