How Blood Flows Through the Heart
http://www.interactive-biology.com - In this video, I go through the process of how blood flows through the heart. It shows blood entering via the vena cave to the Right atrium, then getting pumped into the right ventricle, to the pulmonary vein to the lungs, to the left atria, left ventricle, and then via the aorta to the rest of the body.
