JJ Duke, an assistant professor in Northern Arizona University's Department of Biological Sciences, is studying respiratory mechanics--the "how" of breathing. He wants to understand the underlying ...

The study of respiratory mechanics encompasses the physical principles and physiological processes that govern the movement of air into and out of the lungs. Recent technological advances have enabled ...

A total of 10 obese (38±5% body fat; mean±s.d.) and nine lean (18±4%) men were studied. These data demonstrate that mild-to-moderate obesity in young men results in reduced lung volumes and ...

The respiratory system is responsible for the exchange of carbon dioxide and oxygen in the human body. This system also helps remove metabolic waste products and keep pH levels in check. The major ...
