How does the respiratory system of birds allow them to fly? The respiratory system pumps air into openings in their bones which helps to keep the bird light. It also constantly supplies oxygen to the muscles of the bird, allowing it to fly continuously for long periods of time. ...
An understanding of respiratory tract diseases is extremely important in avian medicine. The upper respiratory system of birds has evolved differently from that of mammals. The changes have produced one of the most efficient respiratory systems among vertebrates. Some of these changes predispose birds ...
Special attention is given to the evolution, the structure, the function and the development of the lung-air sac system. Readers will not only discover the origin of birds but will also learn how the respiratory system of theropod dinosaursworked and may have transformed into the avian one. ...
