Lungs: Defending Airways

May 31, 2023


The lungs exchange carbon dioxide in blood for oxygen in the air we breathe and defend against particulates, toxins, and infectious organisms

Let’s take a deep breath and fill our lungs with air. Ahh, doesn’t that feel good? Our lungs are responsible for taking in oxygen from the air we breathe and distributing it to organs throughout our bodies and then ridding those organs of carbon dioxide. Get ready to dive into a fascinating episode on our lungs and how they protect us against particles, toxins, and infectious organisms in the air we breathe. The tinier the foreign particle, the more harmful they are! Let’s explore the superhero-like abilities of these incredible organs, our lungs.

On This Episode We Discuss:

  • The functions of the lung
  • The anatomy of the lung
  • Gas exchange
  • The pulmonary vascular system
  • Systems that protect the lung from particulates, toxins, and infectious organisms
  • Pulmonary function tests
  • Stay away from smoking

The host of the show is Dr. Stanley Crooke, a scientist, a physician, an entrepreneur and the father of antisense technology. Dr. Crooke is responsible for driving the development of antisense or ASO technology, an RNA-targeted technology responsible for the commercialization of three best- and first-in class medicines and more than 40 drugs in development. In 2020, Stan formed n-Lorem to use this powerful technology to develop experimental personalized ASO medicines for nano-rare patients (1 to 30 patients worldwide) for free, for life.
