Inhaled oxygen diffuses through the walls of the alveoli in the lungs, then into the bloodstream where it binds to hemoglobin in red blood cells for transportation to tissues and cells in the body.
Oxygen and water vapor are molecules that diffuse out of a leaf through tiny pores called stomata. Oxygen is produced during photosynthesis, while water vapor is a byproduct of transpiration, the process where plants lose water through their leaves.
Oxygen flows into the body through the respiratory system. When we breathe in, oxygen is inhaled through the nose or mouth, travels down the trachea, and then into the lungs where it is absorbed into the bloodstream and carried to the body's cells.
No, fat particles are too large to diffuse easily through the cell membrane. Oxygen particles, being smaller, can diffuse freely into cells for cellular respiration.
The respiratory system absorbs oxygen. Oxygen is inhaled through the nose and mouth, passes through the trachea, and enters the lungs where it is absorbed into the bloodstream through tiny air sacs called alveoli.
After being inhaled through the mouth, oxygen travels down the trachea (windpipe) and enters the lungs. In the lungs, the oxygen diffuses into the bloodstream through the alveoli, small air sacs where gas exchange occurs. The oxygen is then carried by red blood cells to tissues and organs throughout the body for cellular respiration.
Inhaled oxygen will diffuse through the walls of the lungs. It will also diffuse through the walls of red blood cells so it can be carried all over the body.

Oxygen and carbon dioxide are moved to and from body tissues via the circulatory system. These materials diffuse through the cell membrane, and then diffuse through the capillary wall into or out of the bloodstream.

oxygen that is inhaled into the lungs is diffused through the small air sacs, called alveoli, into the bloodstream.
Substances that are small, nonpolar, and uncharged will diffuse through a membrane easily. This includes gases like oxygen and carbon dioxide, as well as small lipophilic molecules. Larger or charged molecules may require assistance from transport proteins to cross the membrane.
Oxygen can diffuse into a unicellular organism through its cell membrane. The organism utilizes this oxygen for cellular respiration to produce energy.
