Understanding Blood Flow Through the Heart

This video from Moomoomath and Science explains the flow of blood through the heart, highlighting its importance in transporting oxygen, removing carbon dioxide, fighting disease, and delivering nutrients. It details the journey of blood through the right side of the heart to the lungs, where carbon dioxide is exchanged for oxygen, and then through the left side of the heart to the rest of the body. The video concludes with a brief channel promotion.
