El sistema circulatorio: cómo el corazón bombea vida

The video explains the heart's continuous beating and its role in pumping blood throughout the body. It describes the heart's structure, including its two sides and compartments, and how it receives oxygen-rich blood from the lungs to distribute it through arteries and capillaries. The video also covers how blood returns to the heart via veins, carrying carbon dioxide to the lungs for oxygen exchange. The heart and blood vessels form the circulatory system, with the heart beating 100,000 times a day, totaling over 3 billion beats in a lifetime.
