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 during external respiration?
During external respiration, carbon dioxide is released from the body by diffusing from the blood into the alveoli in the lungs. It is then exhaled out of the body during the process of breathing.
What gases are begin exchanged in the alveoli?
Mostly oxygen & carbon dioxide - but also some nitrogen.
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
Where in our breathing system does the changes of oxygen and carbon dioxide dioxide happen?
The exchange of oxygen and carbon dioxide occurs in the alveoli of the lungs. Oxygen is taken up from the air into the bloodstream, and carbon dioxide is released from the bloodstream into the air in the alveoli during respiration.
What happens in the alveoli-?
Gaseous exchange takes place in the alveoli where carbon dioxide from the bloodstream diffuses into the air.
What happens to Carbon dioxide in the blood that flows in the alveoli?
it filters your lungs which causes you to exhale
The carbon dioxide is carried by the blood back to the alveoli where it is released into the lungs to be what?
exhaled
Does carbon dioxide pass into the blood?
Carbon dioxide passes into the blood at the capillaries of the systemic circulation. Then it is released at capillaries around the alveoli.
What happens to carbon dioxide in the blood that flows threw alveoli?
it filters your lungs which causes you to exhale
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.
How do lungs remove its carbon dioxide?
Lungs remove carbon dioxide from the body by exchanging it with oxygen during the process of breathing. When we inhale, oxygen is taken in and carbon dioxide is released. The carbon dioxide is then expelled from the body when we exhale.
