it filters your lungs which causes you to exhale
When we inhale in and out oxygen moves from the alveoli to blood carbon dioxide moves from blood to alveoli.
alveoli take co2 from your blood and turns it into gas
oxygen enters the blood and carbon dioxide
it filters your lungs which causes you to exhale
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.
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.
It happens in the alveoli of the lungs
carbon dioxide
yes
Alveoli
alveoli
The exchange of oxygen and carbon dioxide happens in between the alveoli and then through the walls of the capillaries and then into the blood. The oxygen is then picked up by hemoglobin in the red blood cells and sent to all body cells. While this is happening the carbon dioxide is transported back from the body cells and into the blood. It diffuses through the walls of the capillaries and into the walls of the alveoli. Carbon dioxide leaves your body whenever you breathe out.
