RESPIRATION

1986
This chapter discusses the respiratory system of giraffes. The respiratory system supplies oxygen, removes of carbon dioxide and produces the airflow needed to make sounds. Giraffes do not have the velocity of airflow through the airways to vibrate vocal cords sufficiently to generate sounds able to be heard by humans but can produce sounds able to be ...

Respiration

2000
The primary function of the respiratory system is gas exchange—delivering oxygen from the environment to the tissues, and removing carbon dioxide from the tissues. Maintaining a constant and high body temperature and exercise in flight create very high demands for oxygen delivery, and birds have evolved a unique respiratory system to meet these demands.

RESPIRATION OF INSECTS

Science, 1927
These experiments would seem to prove that no special spiracles are used for inhaling and others used for exhaling, but rather that all are alike in this respect, as the abdomen expands air is taken in and as the body contracts the gases are exhaled.

Optimal respirator settings in assisted respiration

Medical & Biological Engineering, 1974
An analysis of assisted respiration, based on a linear, first-order lung model, has been performed using rectangular, sine and ramp input pressure waveforms. The results of the analysis have been applied to predict optimal respirator settings. The criterion of a simultaneous minimisation of the average alveolar pressure and ventilatory work per minute ...
