It is through this mechanism that blood is oxygenated and carbon dioxide, the waste product of cellular respiration, is removed from the body. The function of the respiratory system is to exchange two gases: oxygen and carbon dioxide. The trachea is a flexible airway supported by the cartilage rings, which prevents the trachea from collapsing when the air pressure inside falls while breathing in. External respiration occurs as a function of partial pressure differences in oxygen and carbon dioxide between the alveoli and the blood in the pulmonary. At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting. by Haiden Heath How are oxygen and carbon dioxide exchanged in the respiratory system Gas Exchange Between Alveolar Spaces and Capillaries. Transcription and Translation in Prokaryotes JWhat is it called when oxygen and carbon dioxide are exchanged between the alveoli and the blood This exchange of oxygen and carbon dioxide is called respiration.
