What else can I help you with?
Do alveoli have C shaped rings around them?
Alveoli are surrounded by capillaries so that the oxygen can diffuse into the blood and carbon dioxide can diffuse out. I think it depends on the shape of the alveoli to the path of the capillary.
Where does carbon dioxide diffuse into the blood during the process of respiration?
Carbon dioxide diffuses into the blood in the capillaries surrounding the alveoli in the lungs during the process of respiration.
Do oxygen and carbon dioxide pass through the walls of the trachea?
No, the trachea is a passageway for air to travel to and from the lungs. Oxygen and carbon dioxide are exchanged in the alveoli of the lungs, where they diffuse across the walls of the alveoli and capillaries.
Does the carbon dioxide travels into capillaries alveolar and out of the capillaries at the tissue?
In the alveoli
How are oxygen and carbon dioxide exchanged between the alveoli and the capillaries?
Oxygen diffuses from the alveoli into the capillaries, where it binds to hemoglobin in red blood cells for transport to tissues. Carbon dioxide diffuses from the capillaries into the alveoli and is exhaled from the body.
What are the small sacs in the lungs where carbon dioxide is exchanged for oxygen?
The humorus
Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
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.
How does carbon dioxide get out of your blood?
Diffusion in the capillaries of the alveoli in the lungs.
Where does the diffusion of oxygen and carbon dioxide occur?
In the lungs, the diffusion of oxygen occurs from the alveoli (air sacs) into the blood capillaries, while the diffusion of carbon dioxide occurs from the blood capillaries into the alveoli for exhalation. This exchange process is facilitated by differences in partial pressures of oxygen and carbon dioxide between the air in the alveoli and the blood in the capillaries.
Which way would O2 and CO2 diffuse during internal respiration?
O2 would diffuse into the cells, and CO2 would diffuse into the systemic capillaries.
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.
