What function do the alveoli perform?(1 point)
The alveoli perform the function of gas exchange in the respiratory system. Oxygen from inhaled air diffuses into the bloodstream and carbon dioxide, a waste product, diffuses out of the bloodstream into the alveoli to be exhaled.

The function of the alveoli is to facilitate the exchange of gases (specifically oxygen and carbon dioxide) between the respiratory system and the bloodstream.
is carbon dioxide in the air or the blood stream
Carbon dioxide is primarily found in the bloodstream. It is produced as a waste product during cellular respiration and is transported through the bloodstream to the lungs. In the alveoli, carbon dioxide diffuses from the bloodstream into the lungs to be exhaled. However, there is also a small amount of carbon dioxide present in the air due to human respiration and other sources.
The function of alveoli is to facilitate the exchange of oxygen and carbon dioxide between the lungs and the bloodstream.
The alveoli are small air sacs found in the lungs responsible for gas exchange. They play a vital role in the respiratory system by facilitating the exchange of oxygen and carbon dioxide between the lungs and the bloodstream.
To understand the function of alveoli, it is helpful to have a basic understanding of the structure of the respiratory system. The respiratory system consists of the airways (nose, mouth, and throat), lungs, and blood vessels. When we breathe in, air enters the nose or mouth, travels down the throat, and enters the lungs through the airways.
Within the lungs, the bronchi (large airways) branch out into smaller tubes called bronchioles. At the end of the bronchioles, thin-walled alveoli are present. These alveoli are surrounded by a network of blood capillaries.
During inhalation, oxygen-rich air enters the alveoli, while during exhalation, carbon dioxide is expelled from the body. The alveoli's function is to facilitate the exchange of these gases across their thin walls. Oxygen from the air in the alveoli passes through the walls into the capillaries and binds to red blood cells, which are responsible for transporting oxygen to the body's tissues. Meanwhile, carbon dioxide, a waste product of metabolism, diffuses from the capillaries into the alveoli and is expelled when we exhale.
This oxygen-carbon dioxide exchange in the alveoli is essential for maintaining proper oxygen levels in the bloodstream and removing waste carbon dioxide. Without functioning alveoli, the body would not receive adequate oxygen, leading to respiratory problems and potentially life-threatening conditions.
