The skin is not just a simple thin covering which keeps the body together. The skin is a combination of tissues that perform functions necessary for human survival. Our skin helps maintain body temperature, receives stimuli from the environment, and stores chemical compounds. Consider the human predicament if the skin were not waterproof! Every time it rained, each human would absorb water like a sponge. The skin also acts as a protective covering keeping underlying tissues from bacterial invasion and harmful light rays and from drying out. As a medical specialist, it is important for you to understand the complex functions of the skin. Occasional references to military terminology or combat situations do not detract from the lesson's relevance for civilian medicine and health care. |
