About this episode

In this episode, Audra and her kids explore the heart's double pump and its role in the body's systems.

❤️ After last episode, did you start to wonder WHY the heart has two tracks for pumping blood? 🫀 In this episode of What’s Happening Inside Me?, Audra is joined by her kids, Sloane and Ransom as they dive deeper into the amazing double-pump heart. Building on last week’s episode, they explore why the heart pumps blood in two separate loops—one delivering oxygen to the whole body, and the other refilling blood with oxygen in the lungs. Using fun metaphors and kid-friendly explanations, they connect the heart to other systems in the body, including: Cells and mitochondria, the body’s energy factories Blood vessels, highways that carry oxygen and glucose The lungs, where blood picks up oxygen and drops off carbon dioxide The digestive system, which provides glucose to make energy This episode is perfect for curious kids who love learning how everything in the body works together as a team. 🫀 In This Episode, Kids Will Learn: How the heart’s double pump works Why blood travels on two separate tracks How oxygen and glucose get to the cells to make energy How the body gets rid of carbon dioxide waste How multiple systems in the body work together 🎧 Helpful to Know Builds on ideas…
