What else can I help you with?
Describe what happens in the alveoli sacs?
When we inhale in and out oxygen moves from the alveoli to blood carbon dioxide moves from blood to alveoli.
What happens to carbon dioxide in the blood that flows through the capillaries in the alveoli?
alveoli take co2 from your blood and turns it into gas
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.
What happens to Carbon dioxide in the blood that flows in the alveoli?
it filters your lungs which causes you to exhale
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.
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.
What system allows for the exchange of carbon dioxide and oxygen between the air and the blood?
It happens in the alveoli of the lungs
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.
Where does the exchange of oxygen and carbon dioxide between the air and blood occur in humans?
The exchange of oxygen and carbon dioxide between the air and blood occurs in the alveoli of the lungs. Oxygen from the air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.
How does the body exchange carbon dioxide in the blood?
alveoli
Where the carbon dioxide and blood exchanged in the body?
Alveoli
Which gas passes out of the blood to the alveoli?
carbon dioxide
