What else can I help you with?
What gas enters the alveoli?
Oxygen is removed from the alveoli by the cappillaries.
In the lungs is carbon dioxide more concentrated in the alveoli or in the blood?
In the lungs, carbon dioxide is concentrated more in the blood. The alveoli keeps the carbon dioxide at a lower level than in the blood.
Does the exchange of carbon dioxide depend on the concentration of oxygen in the alveoli and the blood?
No. It depends on the concentration of carbon dioxide in the alveoli and the blood. The concentration of carbon dioxide in the capillaries of the alveoli is higher than the concentration of carbon dioxide in the air, so carbon dioxide in the capillaries of the alveoli diffuses out of the capillaries into the alveoli of the lungs and is exhaled.
Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
What is the place were oxygen enter the blood and carbon dioxide leaves the blood?
The place is the same for both; the alveoli in the lungs.
Where does oxygen enter the blood and carbon dioxide leaves it?
Oxygen enters the blood through the alveoli in the lungs during inhalation, where it diffuses into the bloodstream. Carbon dioxide leaves the blood in the same location, diffusing from the blood into the alveoli to be exhaled during exhalation.
What does the Alveoli and the capillaires do?
Alveoli takes oxygen in and brings out carbon dioxide.
Where does the exchange of oxygen carbon dioxide in the blood happen?
The exchange of oxygen and carbon dioxide in the blood occurs in the capillaries surrounding the alveoli in the lungs. Oxygen diffuses from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli to be exhaled.
What is the scientific name for alveoli?
The scientific name for alveoli is "pulmonary alveoli." They are small air sacs within the lungs where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.
Carbon dioxide enters bloodstream through the air sacs?
Yes, carbon dioxide diffuses from the alveoli in the lungs into the bloodstream. This gas exchange occurs due to differences in partial pressures of carbon dioxide between the alveoli and the blood. Once in the bloodstream, carbon dioxide is transported to the lungs to be exhaled out of the body.
Why does oxygen and carbon dioxide move from the alveoli into the blood stream?
Oxygen moves from the alveoli into the bloodstream through diffusion, where it crosses the thin walls of the alveoli and capillaries. Similarly, carbon dioxide moves from the bloodstream into the alveoli for removal when blood with high levels of carbon dioxide comes into contact with alveolar air with lower levels of carbon dioxide.
What is the function of alveoli in the respiratory system?
The alveoli are tiny air sacs in the lungs where oxygen is taken in and carbon dioxide is released during the process of breathing. They are responsible for the exchange of gases between the lungs and the bloodstream, allowing oxygen to enter the body and carbon dioxide to be removed.
