How does your body deliver oxygen to over 30 trillion cells every second without failure? In this video, we explore the astonishing engineering behind respiration—from the half–tennis court surface area of your alveoli to hemoglobin’s iron-regulated oxygen transport system and the cardiovascular control mechanisms that instantly redirect blood flow when you sprint. ATP synthase turbines inside each cell depend on a nonstop oxygen supply, yet the body cannot store oxygen. Is this intricate cascade of interdependent systems the result of undirected evolution, or does it point to intentional design? This deep dive examines the science behind one of life’s most critical challenges.

The full episode features engineer Steve Laufmann and medical doctor Howard Glicksman.
