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.
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.
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
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.
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.
What are the small sacs in the lungs where carbon dioxide is exchanged for oxygen?
The humorus
Which way would O2 and CO2 diffuse during internal respiration?
O2 would diffuse into the cells, and CO2 would diffuse into the systemic capillaries.
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.
Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
Which substances are exchanged between the blood in the capillaries and the air in the alveoli?
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.
How does carbon dioxide get out of your blood?
Diffusion in the capillaries of the alveoli in the lungs.
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.
