In this video, Jonathan from the Institute of Human Anatomy explores the incredible ways the human heart adapts and strengthens with exercise. Through a cadaver dissection, we'll uncover what happens inside this tireless organ when it's pushed to its limits. Discover how consistent physical activity can lead to a more efficient and powerful heart, including fascinating insights into stroke volume, cardiac output, and the cellular changes within the myocardium.
