Capillaries
The tiny air sacs of the lungs were oxygen and carbon dioxide are exchanged are the alveoli.
The actual air exchange in the lungs takes place in the alveoli, which are tiny sacs at the end of the bronchioles. Oxygen from the inhaled air passes through the walls of the alveoli and into the bloodstream, while carbon dioxide moves from the blood into the alveoli to be exhaled.
The lungs contain air sacs called alveoli which are surrounded by blood capillaries to allow gaseous exchange.
Exchange oxygen and carbon dioxide in the alveoli of the lung, then transfer it to the heart
Alveoli of lungs.
The exchange of gases between blood and air occurs in the alveoli of the lungs. Oxygen from the air diffuses into the bloodstream, while carbon dioxide from the blood diffuses into the air in the alveoli to be exhaled.
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
The alveoli are small sacs within the lungs where gas exchange occurs. They are located at the ends of bronchiole branches.
Gas exchange occurs across the respiratory membrane of the alveoli; however, the short answer is simply alveoli
The sacs in the lungs, called alveoli, have thin walls that allow for the exchange of gases. Oxygen from the air enters the bloodstream through the alveoli, while carbon dioxide from the bloodstream exits the body through the alveoli. This exchange occurs due to the difference in concentration of gases between the air in the alveoli and the blood in the surrounding capillaries.
The air spaces in the lungs are called pulmonary alveoli. They are where gas exchange occurs in the lungs of mammals.
