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.
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.
Oxygen diffuses from the alveoli in the lungs into the surrounding capillaries. The concentration of oxygen in the alveoli is higher than in the blood, so oxygen moves across the thin wall of the alveoli and into the bloodstream through a process called diffusion.
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.
Oxygen moves from the alveoli into the bloodstream through diffusion, where it crosses the thin walls of the alveoli and capillaries. Similarly, carbon dioxide moves from the bloodstream into the alveoli for removal when blood with high levels of carbon dioxide comes into contact with alveolar air with lower levels of carbon dioxide.

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

the blood surround Alveoli in order to gas exchange between the Alveoli and red blood cell.

The humorus
Alveoli absorb oxygen through a process called diffusion, where oxygen in the air within the alveoli moves into the blood in the surrounding capillaries. The thin walls of the alveoli and capillaries facilitate this exchange, allowing oxygen to pass from an area of higher concentration (inside the alveoli) to an area of lower concentration (the blood). Simultaneously, carbon dioxide moves from the blood into the alveoli to be exhaled. This efficient gas exchange is essential for maintaining oxygen levels in the body.
Alveoli are tiny air sacs in the lungs where gas exchange occurs, surrounded by a network of capillaries. When we inhale, oxygen from the air enters the alveoli and diffuses across their thin walls into the adjacent capillaries, where it binds to hemoglobin in red blood cells. This process allows oxygen to enter the bloodstream while carbon dioxide moves from the blood into the alveoli to be exhaled. Thus, alveoli and capillaries work together to facilitate the efficient transfer of oxygen into the bloodstream.
At the boundary between the capillaries and the alveoli, gas exchange occurs through a process called diffusion. Oxygen from the alveoli moves into the blood within the capillaries, while carbon dioxide from the blood is released into the alveoli to be exhaled. This exchange happens across the thin walls of the alveoli and capillaries, which are composed of single layers of cells, facilitating efficient transfer due to the concentration gradients of the gases.
Oxygen moves into the alveoli of the lungs through the process of diffusion. This occurs because of the concentration gradient between the oxygen in the alveoli and the carbon dioxide-rich blood in the surrounding capillaries. As oxygen levels are higher in the alveoli than in the blood, oxygen molecules naturally diffuse from the alveoli into the bloodstream, while carbon dioxide moves in the opposite direction. This exchange is facilitated by the thin walls of the alveoli and capillaries, which allow for efficient gas transfer.
These are called the alveoli capillaries.
Capillaries attach to alveoli through a network of tiny blood vessels that surround each alveolus, facilitating gas exchange. The walls of capillaries and alveoli are extremely thin, allowing oxygen to diffuse from the alveoli into the blood while carbon dioxide moves from the blood into the alveoli. This close proximity and structural arrangement maximize the efficiency of oxygen and carbon dioxide exchange during respiration. The capillary-alveolar interface is crucial for the proper functioning of the respiratory system.
