Guided Notes
Key concepts students will learn:
- •
The largest organ in the human body is the skin, which has a surface area of about 20 square feet in adults.
- •
The four overlapping stages of the skin's regenerative process are hemostasis, inflammation, proliferation, and remodeling.
- •
During hemostasis, a protein called fibrin forms cross-links on the top of the skin to prevent blood from flowing out and bacteria from getting in.
