Unlike veins and arteries, capillaries are responsible for oxygen exchange, or delivering oxygen to organs and tissues throughout the body while shuttling carbon dioxide away. Low blood oxygen can ...

The gas exchange system affects oxygen, nitrogen and carbon dioxide from the air. Find out more with BBC Bitesize in this article for 11-14 year old students.

This physiological process is responsible for bringing oxygen to and removing carbon dioxide from the lungs. Mixed venous blood carries carbon dioxide into the lungs and takes up alveolar oxygen.

Specifically, the delivery of oxygen from lungs to tissues, and the removal of the waste product, carbon dioxide, through exhaling. Recently published online in the journal Proceedings of the National ...

IN a study of the respiration of soils at temperatures ranging from 10° to 70°C, it was found that oxygen uptake and carbon dioxide evolution increased with increasing temperature above 50° C. 1.
