When we exhale /blow out we push out all the carbon dioxide in our lungs!
alveoli
capillaries
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
Simply put, the gas exchange occurs in the lungs. More specifically, the blood exchange occurs at the avoli, the "air sacs" in the lungs where the surrounding capillaries can be oxygenated.
The alveoli are small sacs within the lungs where gas exchange occurs. They are located at the ends of bronchiole branches.
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.
Gas exchange occurs across the respiratory membrane of the alveoli; however, the short answer is simply alveoli
The exchange of gases occurs at the ends of the airways in the lungs. Here tiny sacs called alveoli connect with tiny blood vessels and here exhaust gas [carbon dioxide] is exchanged for fresh gas [oxygen].
RespiratoryOrgans of the respiratory system: nose, pharynx, larynx, trachea, bronchi, alveoli
The structure in the lungs that contains the thinnest epithelium is the alveoli. Alveoli are air sacs where the exchange of gases takes place.
The tiny sacs in our lungs are called 'alveoli' which is what makes gas exchange possible.
Gas exchange occurs in the alveoli of the lungs.
In lungs alveoli is present where exchange of gases takes place, when blood with carbon dioxide is reached lungs then these alveoli purify by removing carbon dioxide
The lungs exchange gases with the air. The lungs will take in fresh, oxygen filled blood and circulate it throughout the body. The lungs will then expel the air, and start the process all over again.
