Anatomy and physiology of the skin

Skin protects the body from physical damage and infiltration by bacteria. It helps the body regulate temperature and is an important part of human sensory perception and communication. This article describes the different layers of the skin and their functions. It also includes a guide to performing a thorough skin assessment, as well as information on common skin problems. Nurses should understand the anatomy and physiology of the skin and be aware of how different conditions affect it, and how these may appear in people with different skin tones. How the ageing process impacts the skin is also described.
