It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).

Oxygen diffuses into the capillaries of the lungs because there is a?
greater concentration of oxygen in the air sacs of the lungs than in the capillaries.
Where do red blood cells drop off oxygen?
Red blood cells release their oxygen in the capillaries. The oxygen diffuses across the capillary wall to reach the body tissues.
Where does most gas exchange between blood and tissue take place?
In the alveoli of the lungs. This is where oxygen diffuses from the lungs into the bloodstream and carbon dioxide diffuses out of the bloodstream and into the lungs.
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.
Where in the lungs does diffusion take place and what gasses are diffused?
---------------------------- The exchange of gasses takes place across the Alveoli, which are air spaces surrounded by very small air sacs and have a rich supply of blood, because they are surrounded by capillaries. The lungs are made up of many alveoli which are the respiratory surface. Oxygen diffuses from the alveoli into the blood in the capillaries and carbon dioxide diffuses from the blood in the capillaries into 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
Is there carbon in our muscles?
It diffuses into capillaries in the muscle where red blood cells and the blood carry it to the lungs were it is released and oxygen takes its place in the blood.
O2 enters the capillaries and ----- from the capillaries passes in to the lungs?
Carbon dioxide is produced as a waste product of respiration, and is taken in the bloodstream to the capillaries outside the lungs, where the CO2 diffuses into the alveoli of the lungs.
What is the major role of the lungs?
The lungs are cavities that allow for the intake of oxygen. They also have a large surface area used by alveoli, sacs lined with capillaries, which are responsible for gas exchange. When the oxygen diffuses into the blood, carbon dioxide is released back into the lungs where it is breathed out.
How do alveoli and capillaries help to get oxygen?
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.
How do the lungs interact with the circulatory system even though they are considered part of the respiratory system?
The purpose of the lungs is to get oxygen into the body and carbon dioxide out of it. It does this by having a generous supply of blood capillaries surrounding each alveolus. When fresh air is drawn into the alveolus oxygen diffuses through into the capillaries and carbon dioxide diffuses the other way. The capillaries are constantly supplied with de-oxygenated blood from the body and the oxygenated blood travels away to the heart and round the body.
What happens to the carbon dioxide produce in the muscles?
It diffuses into capillaries in the muscle where red blood cells and the blood carry it to the lungs were it is released and oxygen takes its place in the blood.
