A semipermeable membrane.
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 typically diffuses the fastest through tissues due to its small molecular size, allowing it to pass through cell membranes easily. This property is essential for efficient delivery of oxygen to cells for physiological processes.
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.
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.
Oxygen gas diffuses faster than air because oxygen molecules are smaller and lighter than the molecules of air, which is mostly composed of nitrogen and oxygen. This allows oxygen molecules to move more quickly through a medium, such as air or other gases.

Alveoli in the lungs.
In the lungs, oxygen diffuses from the alveoli into the bloodstream through the process of gas exchange facilitated by differences in partial pressure.

The placenta is the structure that diffuses nutrients from the mother's blood into the embryo's blood. It allows for the exchange of oxygen, nutrients, and waste products between the mother and the fetus during pregnancy.
