The Heart: The Most Powerful Organ in Our Body?

This DW Documentary explores the human heart, the tireless organ that beats billions of times over a lifetime. It reveals how much stranger and more sophisticated the heart is than we often assume, from its electrical rhythms to its links with the brain and emotions. Drawing on current science, it explains both how the heart works and how modern medicine keeps it going. It is an engaging introduction to the body's most vital muscle.
