What determines whether oxygen and carbon dioxide diffuse into or out of the capillaries of the tissues near alveoli explain?

its the blood which act as a transporter and the concentration of blood determines that oxygen will diffuse faster than carbon dioxide due to its small molecular weight but if diffusion occur in such manner then amount of carbon dioxide will be automatically more. carbon dioxide is a toxic gas and its presence in more amount can causes problems by increasing the PH of blood,but carbon dioxide has an affinity for water. The excess carbon dioxide gets dissolve in water or simply we can say in plasma of blood more than oxygen so its its excrete in lungs and passes from lungs to mouth in atmosphere following bronchioles and bronchi.

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.
Does carbon dioxide diffuse from the capillaries to the alveoli?
yes while oxygen then diffuses into the blood, and carbon dioxide diffuses out. it's a chain
Does the carbon dioxide travels into capillaries alveolar and out of the capillaries at the tissue?
In the alveoli
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).
Why does oxygen diffuse in and carbon dioxide diffuse out?
In the alveoli, oxygen diffuses into the blood that the capillaries carry due to a concentration gradient that exists there as oxygen conc is higher in the alveolar sacs than in the blood capillaries. Similarly carbon dioxide diffuses out of the blood capillaries into the alveolar sacs down the concentration gradient. The constant flow of blood is there to ensure this concentration gradient is established at all times.
How does carbon dioxide get out of your blood?
Diffusion in the capillaries of the alveoli in the lungs.
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.
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 takes place between the alveoli and capillaries in the lungs?
When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream. During the same process, carbon dioxide is outgassed from the blood to the alveoli When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream.

What happens to the air as it travels in the body?
When we breathe oxygen.The oxygen then goes down the trachea and through the bronchiole tubes and into the lungs, where it meets the alveoli. The Oxygen in the alveoli then diffuses through the alveoli and through the capillaries in the lungs. The capillaries are only one cell thick, thus making it easier for the oxygen and carbon dioxide to diffuse through. The carbon dioxide diffuses through, in the other direction from, the capillaries to the alveoli, where it can leave the body via the bronchiole tubes, trachea and exiting out the mouth and we end up breathing out oxygen. Also the name for when we breathe oxygen and and breathe out carbon dioxide is "gas exchange"
Oxygen diffuse into the blood at the alveoli?
Carbon dioxide does.
