The process that moves oxygen across the cell membrane is called simple diffusion. Oxygen molecules move from an area of high concentration to an area of low concentration without the need for energy input. This process helps maintain the balance of oxygen inside and outside the cell for cellular respiration.
This process is called gas exchange. In the lungs, oxygen enters the bloodstream through diffusion across the alveolar membrane, where it binds to hemoglobin in red blood cells for transportation to tissues.
Oxygen moves from the lungs to the blood through a process called diffusion. This occurs at the alveoli in the lungs, where oxygen in the air sacs diffuses across the alveolar membrane into the capillaries surrounding the alveoli. From there, the oxygen binds to hemoglobin in red blood cells for transport to the body's tissues.
Oxygen moves into the blood by diffusing across the respiratory membrane in the lungs. This process occurs in the alveoli, tiny air sacs where oxygen enters the bloodstream from the surrounding air. From there, oxygen binds to hemoglobin in red blood cells for transportation to tissues throughout the body.
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.
Water moves through osmosis from an area of lower solute concentration to an area of higher solute concentration across a semi-permeable membrane. This process helps maintain balance in solute concentrations on both sides of the membrane.
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
This process is called gas exchange. In the lungs, oxygen enters the bloodstream through diffusion across the alveolar membrane, where it binds to hemoglobin in red blood cells for transportation to tissues.
Oxygen and carbon dioxide are the two important gases that diffuse across the respiratory membrane. Oxygen moves from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.

Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
Particles like oxygen are moved into cells through the process of diffusion. This is a passive process where particles move from an area of high concentration to an area of low concentration, crossing the cell membrane. Additionally, specialized proteins like transporters and channels can facilitate the movement of specific particles into cells.
transportation
Diffusion of molecules across the cell membrane is actually a passive process, not active. Active transport, which requires energy in the form of ATP, is a more complex process as it moves molecules against their concentration gradient.
