Alveoli
Carbon di-oxide
Inside the lungs are alveoli (tiny air sacs). This is where oxygen and carbon dioxide are exchanged.
The pulmonary circulation works closely with the respiratory system at the alveoli. There, capillaries are in close proximity to the air sacs, and gases are exchanged at this point.
The tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged are called alveoli. They are surrounded by blood vessels through which gas exchange takes place during the process of respiration.
The air sacs (alveoli) have a very large total surface area and a very good blood supply. There is an exchange of gases between the air sacs and their surrounding capillary blood vessels. Oxygen diffuses from the air sac into the blood. Carbon dioxide diffuses from the blood into the air sac.
Birds typically have nine air sacs: two cervical air sacs, two anterior thoracic air sacs, two posterior thoracic air sacs, two abdominal air sacs, and one interclavicular air sac. These air sacs help birds efficiently exchange gases during respiration and aid in maintaining their lightweight body structure for flight.
alveoli
(Alveoli are the jaw sockets for teeth, or the individual air sacs in the lungs.) "In childhood, more than one tooth can occupy an alveolus." "In each alveolus of the lung, gases are exchanged with the capillary blood."
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.
