Today, we kick off a brand new season of "Up & Atom Science."

This year, it's all about the human body.

Today's topic focuses on lung health and what continuous smoking does to your lungs.

To tell us more, we welcomed in the experts, Troy Thrash, executive director and CEO at the Da Vinci Science Center and Dr. William Burfeind, Chief of Thoracic Surgery at St. Luke's University Health Network.
