Why does blood move forward through the veins?

Because muscles on the outside of the veins help the blood move. Within the veins are tiny one-way valves that normally keep blood flowing back toward the heart. When the blood arrives at the right atrium, it is pulled in by the expansion of the chamber, which lowers the pressure within the atrium.


How do veins help the circulatory system?

Veins carry deoxygenated blood.This carry deoxygenated blood from all over the body to heart where the blood is send to purify in lungs .There blood's pigment haemoglobin traps the blood and the blood gets purified(oxygenated) and carry by arteries.Thus, we can say that the veins has a very important role in blood circulation they transport blood through the body.
