THE INTEGUMENTARY SYSTEM
The main organs of the integumentary system are the
skin, nails, and hair.
SKINFunctions of the skin:
*To cover the body and prevent water loss (elderly individuals have water loss over time …wrinkles)*To protect the body from infection and injury
*It regulates body temperature by getting rid of wastes through sweat (99% of sweat is water)*It receives information from the environment
*It produces Vitamin D.
Burns and injuries
• Individuals that are victims of burns are categorized by degrees.
• 1st degree burn means it is the least severe-the skin top layer has been removed.
2nd and 3rd degreeDEHYDRATION OCCURS. 2nd degree
burns destroy both the top and next layer of skin .Once the epidermis has separated from the raw dermis, the victim begins to lose fluid, heat, and the ability to block infection. The raw nerve cells of the dermis also mean second degree burns are the most painful.
3rd degree burns• This indicates the burn has destroyed both the epidermis
and dermis. The victim has the same trouble with fluid loss, heat loss, and infection that come with second-degree burns. Full-thickness burns also cause nerve death, so the victim may not be able to feel anything in the area of the burn.
