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.

What does oxygen diffuse into?
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.
Where oxygen diffuses into red blood cells and carbon dioxide diffuses out?
This process occurs in the capillaries of the lungs. Here, oxygen from inhaled air diffuses into red blood cells in exchange for carbon dioxide, which then diffuses out of the red blood cells and is exhaled from the body.
Why oxygen diffuses from the alveoli into the blood?
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.
What passes oxygen from the air to the blood?
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.
What happens to the oxygen level in blood as it moves through the lungs?
As blood moves through the lungs, oxygen is exchanged for carbon dioxide. Oxygen diffuses from the air in the lungs into the blood, increasing the oxygen level in the blood. Conversely, carbon dioxide diffuses from the blood into the air in the lungs, decreasing the carbon dioxide level in the blood.
How does ventilation help maintain a difference in oxygen concentration?
As it circulates, the oxygen diffuses into the blood via the alveolar wall, this then transfer the oxygen to the red blood cells, as diffusion occurs at this point, oxygen diffuses from a high concentration to a low concentration, so the oxygen diffuses into the blood whereas the CO2 diffuses into the alveoli and then out of the mouth when we expire.

This process occurs in the capillaries of the lungs. Here, oxygen from inhaled air diffuses into red blood cells in exchange for carbon dioxide, which then diffuses out of the red blood cells and is exhaled from the body.
Because there is more oxygen in an alveolus than in the blood around it oxygen diffuses?
When there is more oxygen in an alveolus than in the blood around it oxygen diffuses from the capillaries to the veins. This is due to the high concentration of oxygen in the alveoli.
Why oxygen diffuses from the alveoli into the blood?
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.
What is a specific molecule that diffuses into the blood at the lungs?
oxygen
Oxygen diffuse into the blood at the alveoli?
Carbon dioxide does.
Which organ in your body diffuses oxygen into your blood stream?
your lungs
What gases are exchanged in the repitory ystem?
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.

Conversely, carbon dioxide diffuses from the blood into the air in the lungs, decreasing the carbon dioxide level in the blood.
What does the oxygen molecule do when it is in the alveoli?
It diffuses into the blood capillaries surrounding the alveoli.
