Bill Nye the Science Guy (1993)

Episode Overview

Discover the fascinating world of skin science, your body's largest organ. If spread out, your skin would cover approximately one and a half square meters. It serves vital functions, preventing dehydration, shielding you from the elements, and blocking harmful bacteria and viruses. Acting as a personal climate control system, your skin regulates temperature through sweating and shivering. When overheated, sweat glands release a mix of water and chemicals to cool you down as it evaporates. Additionally, your skin is packed with thousands of touch receptors, enabling you to discern textures and temperatures, like the difference between a sheet of paper and a wool blanket.
