Human: The World Within


New: Wednesday, May 5 at 8 p.m. and Friday, May 8 at 2:30 p.m.

Take a deep dive into the incredible universe that’s inside the body to discover the biology that all humans share: heart, brain, eyes, blood and tears. “Human: The World Within” uncovers the science behind how our bodies work and how what’s inside powers every moment of our lives. Jad Abumrad, host of the popular podcast “RadioLab,” narrates the journey through this foreign universe and reveals what makes us tick. “Human: The World Within” premieres Wednesday, May 5 with two back-to-back episodes starting at 8 p.m., then Wednesdays from May 12 through June 2 at 9 p.m. on Arizona PBS, PBS.org and the PBS Video app.

In the new science series, the personal profiles of a diverse group of people from around the world become entry points into the inner workings of six bodily systems: nervous, circulatory, digestive, immune, sensory and reproductive. Experts at the vanguard of science and medicine show how the fantastic feats humans are capable of trace back to the body’s incredible resilience.

“’Human: The World Within’ is an emotional and revelatory journey inside our bodies to discover the hidden systems that make us, us,” said Bill Gardner, VP of Programming & Development for PBS. “We’re excited to bring this accessible, engaging and surprising series to our audience as part of our fantastic lineup of science content this spring.”

“I think viewers will be completely in awe of the incredible, almost magical worlds and ecosystems occurring within their own bodies,” adds Executive Producer Jonathan Soule.
