FUNCTIONS OF THE HEART
Arterial blood (red, oxygen-rich blood) flows from the heart to each part of the body to provide oxygen and nutrients. The venous blood (blue, oxygen-poor 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. The arteries and veins are the pipes through which the blood flows. The lungs provide a place to exchange carbon dioxide for oxygen.
