The alveoli is the point where the waste product of respiration (carbon dioxide) and oxygen are diffused into or out of the blood. Oxygen diffuses into the blood stream and are carried to the heart and carbon dioxide is diffused out of the lungs and expired. The alveoli have moist walls and are close to the capillaries which speeds up the process.

∙ 15y agoThe actual exchange of oxygen occurs within the alveoli. Because they are shaped like they are, they INCREASE the surface area of the lungs that are able to absorb oxygen.

Oxygen passes into the capillaries that surround these sac?
Oxygen passes into the capillaries that surround the alveoli. The thin walls of the capillaries make this diffusion easier.
What are the small sacs in the lungs where carbon dioxide is exchanged for oxygen?
The humorus
What does the oxygen molecule do when it is in the alveoli?
It diffuses into the blood capillaries surrounding the alveoli.
What moves into the capillaries from alveoli?
probably oxygen
What moves into the capillaries into the alveoli?
probably oxygen
What is the role of the alveoli in the respite system?
Alveoli exchange Oxygen with blood in capillaries
What is the body organ which oxygen passes through to capillaries?
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
How do alveolar and capillaries work together to provide the muscles with oxygen?
as it moves through blood vessels capillaries in the alveoli walls, your blood takes oxygen from the alveoli and gives off carbon dioxide to the alveoli
Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
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 is the substance that the capillaries absorb from the lungs?
The capillaries absorb oxygen at the lungs. This occurs near the alveoli.
Why do blood capillaries surround alveoli?
The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
