Why is diffusion important?

Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow and lets them get rid of waste products.

How does diffusion occur?

Diffusion occurs when particles spread. They move from a region where they are in high concentration to a region where they are in low concentration. Diffusion happens when the particles are free to move. This is true in gases and for particles dissolved in solutions – but diffusion does not occur in solids.

What are two examples of diffusion in the human body?

Lungs and Gases

Cells require oxygen gas to make energy and the byproduct of making energy is another gas carbon dioxide. Oxygen is needed to sustain cells in organs but carbon dioxide is toxic. These gases enter and exit the body through the lungs by diffusion.
