More Skin

Last week we revealed skin as the largest organ of the body, but we didn’t get into much detail. And so we failed to mention the fact that skin has two distinct layers: the dermis, and the epidermis.

The epidermis, or outermost layer, is responsible for waterproofing us, protecting us from pathogens (bacteria, etc.), and regulating our body temperature. The dermis, or lower layer, is comprised of various types of connective tissue and cushions us from stress and strain.

Between the two layers lies the basement membrane, which controls the traffic of molecules and cells between the dermis and epidermis.
