Blood releases carbon dioxide and acquires oxygen, in the lungs. The opposite exchange takes place throughout the body on a cellular level, as each cell consumes oxygen from the blood and releases carbon dioxide into the blood.
The exchange of oxygen and carbon dioxide in the respiratory system occurs in the lungs, specifically in the pulmonary alveoli or alveolar sacs. Oxygen brought into the lungs diffuses across the alveolar membrane into the nearby, thin-walled capillaries and enters the blood. In the opposite direction, carbon dioxide diffuses across the capillary and alveolar membranes and into the alveolar sacs, from which it is exhaled.
Oxygen exchange takes place in the alveoli of the human respiratory system.
Gas exchange between the respiratory and circulatory systems happens at the capillaries surrounding the alveoli. The alveoli are the tiny air sacs in the lungs.
Gases are exchanged in the lungs.

The respiratory system exchanges oxygen and carbon dioxide.
The respiratory system; the lungs.
During photosynthesis, carbon dioxide and oxygen are exchanged. The plant uses the carbon dioxide for the photosynthesis and expels oxygen.
Inside the lungs are alveoli (tiny air sacs). This is where oxygen and carbon dioxide are exchanged.
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
The alveoli are at the end of the respiratory tree and is where oxygen and carbon dioxide are exchanged between the lungs and the blood.
