How Blood Flows Through the Heart

In this episode of Interactive Biology TV, Leslie Samuel explains how blood flows through the heart, marking the start of the circulatory system series. The video covers the anatomy of the heart, including the atria, ventricles, and various valves such as the tricuspid, bicuspid, mitral, aortic, and pulmonary valves. It details the one-way flow of blood through the heart, starting from the vena cava, through the right atrium and ventricle, to the lungs, and back through the left atrium and ventricle to the aorta. The video emphasizes the simultaneous contraction of atria and ventricles, ensuring efficient blood circulation to the lungs and the rest of the body.
