How a wound heals itself – Sarthak Sinha

Sarthak Sinha | TED-Ed

View full lesson: http://ed.ted.com/lessons/how-a-wound…

Our skin is the largest organ in our bodies, with a surface area of about 20 square feet in adults.

When we are cut or wounded, our skin begins to repair itself through a complex, well-coordinated process.

Sarthak Sinha takes us past the epidermis and into the dermis to investigate this regenerative response.
