In the lungs, oxygen diffuses from the alveoli into the bloodstream through the process of gas exchange facilitated by differences in partial pressure.
The flow of blood in the body is facilitated by the pumping action of the heart, which carries oxygenated blood from the lungs to the rest of the body and returns deoxygenated blood to the lungs for reoxygenation. Gas exchange occurs primarily in the alveoli of the lungs, where oxygen from the air diffuses into the bloodstream and carbon dioxide is released from the blood into the air to be exhaled.
The actual sites of gas exchange within the lungs are the alvioli.
The gas exchange that takes place in the lungs are carbon dioxide and oxygen.
Alveolar gas exchange takes place in the alveoli, which are tiny air sacs located at the ends of the bronchioles in the lungs. These structures are surrounded by a network of capillaries, allowing for the diffusion of oxygen into the blood and the removal of carbon dioxide from the blood. This exchange is facilitated by the thin walls of the alveoli and the capillaries, maximizing the surface area for gas exchange.
The efficiency of gas exchange in the lungs of vertebrates is greater because it increases the lungs' internal surface area.
