Oxygen diffuses from the alveoli into the blood because of a concentration gradient. The partial pressure of oxygen in the alveoli is higher than in the blood, so oxygen moves across the thin membrane of the alveoli into the blood to reach equilibrium.
The exchange of oxygen and carbon dioxide between the air and blood occurs in the alveoli of the lungs. Oxygen from the air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.
Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
Oxygen is passed from the air to the blood through the process of diffusion in the alveoli of the lungs. The alveoli are surrounded by tiny blood vessels called capillaries, where oxygen diffuses into the bloodstream and carbon dioxide diffuses out of the bloodstream to be exhaled.
Oxygen diffuses into the blood from the alveoli in the lungs during the process of respiration. This occurs due to the difference in oxygen concentration between the alveoli and the blood in the capillaries surrounding them. The oxygen then binds to hemoglobin in red blood cells for transport to tissues and cells throughout the body.
The exchange of oxygen and carbon dioxide in the blood occurs in the capillaries surrounding the alveoli in the lungs. Oxygen diffuses from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli to be exhaled.
Carbon dioxide does.
It diffuses into the blood capillaries surrounding the alveoli.
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.

The alveoli is the division of the respiratory system where gas exchange with the blood occurs. Oxygen from the inhaled air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide diffuses from the blood into the alveoli to be exhaled.
Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.
The exchange of oxygen and carbon dioxide in the blood occurs in the capillaries surrounding the alveoli in the lungs. Oxygen diffuses from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli to be exhaled.
This is the alveoli, which are tiny air sacs in the lungs where gas exchange occurs. Oxygen diffuses from the air into the blood, while carbon dioxide diffuses from the blood into the air in the alveoli.
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.
