Could Humans Ever Breathe Water?

The video explores the concept of breathing underwater and introduces liquid ventilation as a potential solution. While humans can't extract oxygen from water, liquid ventilation using perfluorocarbons (PFCs) could help in medical scenarios and space exploration. PFCs can carry more oxygen than blood, but their viscosity poses challenges in clearing carbon dioxide. Partial liquid ventilation shows promise for treating lung injuries and premature babies. The future may see liquid breathing aiding in exploring distant planets.
