Alveoli
--it is in the alveoli where the exchange of gases occur.. :))
carbon dioxide and oxygen
The respiratory and circulatory systems are involved in the exchange of gases between the alveoli and blood. The alveoli are part of the lungs, and their surrounding capillaries are part of the circulatory system.
Mostly oxygen & carbon dioxide - but also some nitrogen.
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.
Alveoli are site of gas exchange. Actual diffusion of gases occurs at interstitial space between capillaries and alveolar cells.
Gaseous exchange takes place in the alveoli in the lungs, Oxygen is inhaled while Carbon dioxide is exhaled.
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
The humorus
The gases that are exchanged are oxygen and carbon dioxide.
