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.
What else can I help you with?
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
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.
What is the role of the alveoli in the respite system?
Alveoli exchange Oxygen with blood in capillaries
What moves into the capillaries into the alveoli?
probably oxygen
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
What process is used to move oxygen into the capillaries of the lungs?
The process used to move oxygen into the capillaries of the lungs is called diffusion. Oxygen in the alveoli of the lungs moves across the thin walls of the alveoli and the capillaries by diffusion, from an area of high concentration to an area of low concentration, facilitated by the pressure difference between the alveoli and the blood in the capillaries.
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.
Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
