Your body vs. implants

Insulin pumps improve the lives of millions of people with diabetes around the world by monitoring blood sugar, delivering insulin, and preventing the need for constant finger-pricking. But there's a catch: they're temporary. And it's not only insulin pumps that have this problem, but all bodily implants. Why is that? Kaitlyn Sadtler details how our immune system reacts to foreign bodies. [Directed by Andrew Foerster, narrated by Bethany Cutmore-Scott].
