1. The importance of Diffusion

2. Diffusion Recap Diffusion:
The movement of particles from an area of higher concentration to an area of lower concentration.

3. Why is it so important?

4. Nutrient Diffusion
Nutrients from our food diffuse into our bloodstream through the villi in our small intestine.

5. Real-world Application
Transdermal Patch: Delivers medicine into the human body through the skin using the principles of diffusion.

6. What If?
Think-Pair-Share Activity: What if diffusion were reversed? So that particles went from a lower concentration to a higher concentration?
