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 ...

This investigation deals with the temporal aspects of air volume changes during speech. Speech respiration differs fundamentally from resting respiration. In resting respiration the duration and velocity of inspiration (air flow or lung volume change) are in a range similar to that of expiration.

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.

Obstetrical & Gynecological Survey, 1963
SummaryIn 32 cases the oxygen and carbon dioxide content of the umbilical vessels was analysed. In 17 of these cases pH, Pco2 and non‐respiratory acid base balance was also studied. The results show that the placenta, even at the final stage of delivery, is effective as regards O2 and CO2 diffusion.

Optimal respirator settings in assisted respiration
Medical & Biological Engineering, 1974An 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 ...
