  1. Analyze the functions of the integumentary system.

  2. Skin = Integument = Cutaneous Membrane 7 Functions of skin: • Protective covering • Regulates body temperature • Manufactures Vitamin D 4. Sensory function (touch)

  3. 5. Temporary storage of fat, glucose, water and salts 6. Screens out harmful ultraviolet radiation 7. Absorbs topical drugs

  4. Intact skin is the best protection against pathogens, toxins and water loss. • Skin generally is too dry for microbial growth – they do grow in moist areas! • Most skin bacteria is associated with hair follicles or sweat glands. • Underarm odor is caused by a bacteria and perspiration mix.

  5. The best way to prevent the spread of disease is by hand washing.

  6. Follow these four simple steps to keeping hands clean: • Wet your hands with warm running water. • Add soap, then rub your hands together, making a soapy lather. Do this for at least 15 -20 seconds, being careful not to wash the lather away. Wash the front and back of your hands, as well as between your fingers and under your nails. • Rinse your hands well under warm running water. Let the water run back into the sink, not down to your elbows. • Dry hands thoroughly with a clean towel. Then turn off the water with a clean paper towel and dispose in a proper receptacle.
