What is the process by which oxygen and carbon dioxide move across the alveoli?
Raeann22
It is the process of simple diffusion. The movement of oxygen from a high level (in the air) to a lower level (in the blood). The opposite occurs for carbon dioxide which is higher in the blood but lower in the air.

What body system is involed removing carbon dioxide?
The respiratory system is involved in removing carbon dioxide from the body. Carbon dioxide is carried to the alveoli by the circulatory system. There, it diffuses across the membrane into the alveoli and is exhaled.
By what process does the exchange of oxygen and carbon dioxide take place?
capillaries and the alveoli
What happens in the aveoli?
Carbon dioxide diffuses from the capillaries surrounding the alveoli into the lungs where it is exhaled, and oxygen diffuses into the capillaries surrounding the alveoli into the bloodstream where it will circulate throughout the body.
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.
Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
Which process drives the gas exchange from the alveoli to the capillaries?
Diffusion is the process that allows the exchange of oxygen and carbon dioxide in the alveoli. This process is one of passive transport.
Does air entering the alveoli have a high level or a low level of carbon dioxide?
The alveoli have high concentrations of oxygen, especially when compared to venous blood. This concentration gradient is why oxygen diffuses across the alveolar wall into the bloodstream.
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 sequence correctly shows the path of carbon dioxide during respiration?
External respiration is the exchange of oxygen and carbon dioxide between the lungs, body and the outside environment; the breathing process known as inhalation and exhalation. Upon inhalation, air enters the body and is warmed, moistened, and filtered as it passes to the alveoli of the lungs. Oxygen diffuses from the alveoli to the bloodstream, then into the red blood cells. Simultaneously, carbon dioxide in the blood is diffused from the blood to the alveoli, and exhalation expels the carbon dioxide from the alveoli.
How do lungs remove its carbon dioxide?
In lungs alveoli is present where exchange of gases takes place, when blood with carbon dioxide is reached lungs then these alveoli purify by removing carbon dioxide
How does carbon dioxide gets out through the cardiovascular and the respiratory systems?
The blood carries carbon dioxide waste from the tissues where it's generated. When this carbon dioxide reaches the capillaries at the alveoli, it diffuses across the membranes and is released during exhalation.
What does the Alveoli and the capillaires do?
Alveoli takes oxygen in and brings out carbon dioxide.
