Answer 2

Answer:

Substances like carbon dioxide and water can move into and out of cells via osmosis and diffusion. Diffusion is the net movement of molecules from an area of high concentration to an area of low concentration. This occurs in the lungs, between the alveoli and their surrounding capillaries. When we breathe in, oxygen fills the alveoli.
