					THE INTEGUMENTARY SYSTEM
THE INTEGUMENTARY SYSTEM
 IS MADE OF THE FOLLOWING:

             •   Integument (skin)
             •   Hairs
             •   Sweat Glands
             •   Oil Glands
  INTEGUMENTARY SYSTEM
• Largest organ in the body.
• Covers an area of 18-20 square feet.
• Weighs approximately 6 pounds.
        FUNCTIONS OF THE
     INTEGUMENTARY SYSTEM

• Protection
• Excretion
    – Salt, water, wastes
•   Sensation
•   Immunity against disease
•   Maintaining homeostasis
•   Synthesis
    – Vitamin D
LAYERS OF SKIN
       • EPIDERMIS
        – “epi” means
          outer/over
       • DERMIS
       • SUBCUTANEOUS
         LAYER
        – HYPODERMIS
                 THE EPIDERMIS
                   has 5 layers
• Stratum Corneum
    – flattened & dead skin
•   Stratum Lucidum
•   Stratum Granulosum
•   Stratum Spinosum
•   Stratum Basale
    – New skin that has just
      formed
THE DERMIS
     • Contains many fibers
       and cells
     • Is made of 2 Regions:
       – Papillary Region
       – Dermal Region
   PAPILLARY REGION OF THE
           DERMIS
• Binds dermis to
  epidermis
• Gives skin its
  toughness and
  flexibility
• Contains blood
  vessels that supply
  nutrients to the skin.
DERMAL REGION OF DERMIS
           • Sebaceous Glands
           • Sudoriferous Glands
           • Sweat Gland Ducts
               – Tubes take sweat to
                 surface
           •   Sweat Gland Pores
           •   Melanocytes
           •   Hair Follicles
           •   Hair Shaft
           •   Arrector Pillae muscle
           •   Pacinian & Meisner’s
               Corpuscles
THE SUBCUTANEOUS LAYER

• This lies beneath the
  dermis and consists
  of loose connective
  tissue and adipose
  tissue.
• It helps insulate the
  body and conserve
  heat.
ADDITIONAL TERMINOLOGY
           •   Sebum
           •   Melanin
           •   Sweat
           •   Eccrine Sweat Glands
           •   Apocrine Sweat
               Glands
