How do birds breathe so efficiently? Looped airways facilitate air flows
Birds breathe with greater efficiency than humans because of the structure of their lungs –looped airways that facilitate air flows that go in one direction — a team of researchers has found. The results appear in Physical Review Letters. The U.S. National Science Foundation -funded study, conducted by scientists at New York University and the New Jersey Institute of Technology, points to smarter ways to pump fluids and control flows in applications such as respiratory ventilators…Read the full story at https://www.webwire.com/ViewPressRel.asp?aId=272161
