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.

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.
What is the process by which oxygen and carbon dioxide move across the alveoli?
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.
How lungs keep carbon dioxide concentrationdown to certain levels?
lungs contain a special sac like organ known as alveoli which helps in mantaining CO2 and O2 level in the body by diffusing them from the blood to the alveoli and alveoli to the blood respectively
What is a function of a respiratory system?
Human respiration, as a person takes a breath in the air rushes into the lungs causing the alveoli to expand. The alveoli are like little balloons with air on the inside and tinny blood vessels, called capillaries, surrounding the outside. The lungs expand as the alveoli fill up with air. The concentration of oxygen in the air of the alveoli is higher than the concentration of oxygen in the blood inside the capillaries, which results in oxygen diffusing from the alveoli into the capillaries. At the same time the carbon dioxide level in the capillaries is high and low in the lungs. So carbon dioxide also diffuses, but in the opposite direction! (carbon dioxide leaves the capillaries and goes into the alveoli) When a person exhales the lungs decrease in size as the air rushes out. Quick over view, breathe in: Oxygen from the alveoli diffuses (enters) into the capillaries Carbon dioxide from the capillaries diffuses (enters) into the alveoli to be exhaled out. (note: water vapor is also exhaled out with the carbon dioxide, that is what you see on a cold winter day when you exhale) or CO2 (carbon dioxide) + H2O (water) vapor out O2 (oxygen) in

Explain how gases are exchanged at the alveoli?
The exchange of carbon dioxide and oxygen occurs in the alveoli. Each alveolus is surrounded by a network of small blood vessels. Like the alveoli, these small blood vessels have extremely thin walls. Blood that enters the vessels has a high level of carbon dioxide, which it picked up from the body tissues. It contains little oxygen. The carbon dioxide leaves the blood and moves through the walls of the blood vessels and alveoli into the lungs. Oxygen from the air in the lungs then passes through the walls of the alveoli and blood vessels and into the blood. The blood, now rich in oxygen, leaves the lungs and travels to the heart. The heart then pumps it to cells throughout the body. The carbon dioxide is finally expelled from the lungs when we exhale.By ichigo kurosaki
What is the pH level of carbon dioxide gas?
The pure and dry carbon dioxide gas has no pH level.
Where in the respiratory system are oxygen and carbon dioxide exchanged?
Blood releases carbon dioxide and acquires oxygen, in the lungs. The opposite exchange takes place throughout the body on a cellular level, as each cell consumes oxygen from the blood and releases carbon dioxide into the blood.
Does the blood coming from the heart have a high level or low level of carbon dioxide?
Low level of carbon- dioxide and more level of oxygen.
Where Oxygen and carbon dioxide is exchanged at a cellular level by a process called what?
The exchange of oxygen and carbon dioxide occurs through the mechanism of diffusion. The gases diffuse across the thin walls of the capillaries, both in the body tissues and in the capillaries surround the alveoli in the lungs.
How does ground level carbon dioxide reach the ozone layer?
Ground level carbon dioxide is a pollutant. It reaches to atmosphere by westerly's.
How does growing more crops affect level of carbon dioxide in the atmosphere?
Carbon dioxide is decreased.
