Ecosystem-Level Controls on Root-Rhizosphere Respiration [PDF]
New Phytologist, 2013 Recent advances in the partitioning of autotrophic from heterotrophic respiration processes in soils in conjunction with new high temporal resolution soil respiration data sets offer insights into biotic and environmental controls of respiration. Besides

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 ...

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.

SummaryIn 32 cases the oxygen and carbon dioxide content of the umbilical vessels was analysed. In 17 of these cases pH, Pco2 and nonârespiratory 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.
