Arterial blood (red,O2 rich blood) flows from heart to each part of the body to provide oxygen and nutrients. Venus blood (blue, O2poor blood) returns from the body to the heart. The blood then travels through the lungs to exchange carbon dioxide for new oxygen. The heart is a pump which moves the blood. Hope it helps
