How does vasodilation decrease blood pressure?
A) It increases cardiac output, which means less pressure is required to maintain blood flow to tissues.
B) It increases venous return, which decreases the amount of pressure needed to return blood to the heart.
C) It decreases resistance, which means less pressure is required to overcome the resistance.
D) It slows blood velocity; less velocity requires less pressure.

Vasodilation involves the widening of blood vessels, which decreases the resistance against blood flow. This means that the heart does not have to work as hard to pump blood throughout the body, leading to a decrease in blood pressure.
