Diffusion occurs throughout the human body, and without it, cells and body tissue, dirty atmosphere, oxygen concentration may be low, and the eye can dry out.
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.
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.
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.
yes
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
The lungs diffuse oxygen into the bloodstream. Oxygen from the air we breathe is absorbed into the bloodstream through the walls of the alveoli in the lungs, where it is then carried by red blood cells to be delivered to the body's tissues.
I don't know for sure, but my educated guess is that oxygen does not diffuse through the skin. If it did diffuse through the skin then we probably wouldn't have lungs since we would just absorb it through our skin.
Oxygen (O2)
Diffusion. In the lungs, oxygen will diffuse into de-oxygenated blood (oxygen was removed from the blood in the body) and carbon dioxide will diffuse out of the blood into the lungs and expelled from your body when you breathe out.
Oxygen and carbon dioxide
The semi-permeable membrane in cells. Allows some substances to go through and not others.
