Textbook Question
Chapter 31, Problem 14RQ
Trace the route of inspired air in humans from the nostrils to the smallest chamber of the lungs. What is the “dead air space” of a mammalian lung and how does it affect the partial pressure of oxygen reaching the alveoli? How is this problem partially solved by bird respiratory systems?
