What blood vessels surround the aveoli?
Capillaries The smallest of the blood vessels: capillaries.
What gas leaves the blood in pulmonary capillaries and enters the alveoli?
carbon dioxide
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 alveoli surrounded by?
the blood surround Alveoli in order to gas exchange between the Alveoli and red blood cell.
Has a greater partial pressure in the pulmonary capillaries than in the alveoli so it diffuses into the?
C02:alveoli
How does carbon dioxide get out of your blood?
Diffusion in the capillaries of the alveoli in the lungs.
How it is possible for oxygen to diffuse rapidly into the blood?
Oxygen diffuses rapidly into the blood due to the concentration gradient between the alveoli in the lungs and the blood in the capillaries surrounding them. The alveoli have a high concentration of oxygen, while the blood has a lower concentration, which drives the diffusion of oxygen across the thin walls of the alveoli and capillaries. Additionally, the large surface area and short diffusion distance in the lungs help facilitate the rapid diffusion of oxygen into the blood.
Where does the diffusion of oxygen and carbon dioxide occur?
In the lungs, the diffusion of oxygen occurs from the alveoli (air sacs) into the blood capillaries, while the diffusion of carbon dioxide occurs from the blood capillaries into the alveoli for exhalation. This exchange process is facilitated by differences in partial pressures of oxygen and carbon dioxide between the air in the alveoli and the blood in the capillaries.
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.
What moves into the capillaries into the alveoli?
probably oxygen
How are capillaries related to alveoli?
They're adjacent to one another (for gas diffusion).
What causes oxygen to diffuse into the blood from the alveoli - simplest anwer?
A diffusion gradient.
