Transcript

  • 1. Life Science : 1.4
    The Integumentary System
  • 2. Objectives:
    List four functions of skin.
    Describe the two layers of skin.
    Describe the structure and function of hair and nails.
    Describe two kinds of damage that can affect skin.
  • 3. Functions of Skin
    Integumentary system
    Organ system that forms a protective covering on the outside of the body.
    Made up of your skin, hair, and nails.
    Skin protects you by
    Keeping water in your body and foreign particles out of your body.
    Nerve endings in your skin let you
    Feel things around you.
    Skin helps regulate
    Your body temperature.
    Skin Also helps
    Get rid of waste chemicals in sweat.
    Melanin
    Determines color of skin
  • 4. Layers of Skin
    Epidermis
    Outermost layer of skin.
    Most cells in the epidermis are dead.
    Thick as only 2 sheets of paper.
    Keratin
    Protein that makes skin tough.
    Dermis
    Thicker layer of skin that lies beneath the epidermis.
    Collagen
    Protein fibers giving skin strength.
  • 5.
  • 6. Hair and Nails
    Hair helps
    Protect skin from ultraviolet light
    Regulate body temperature in most mammals.
    Keep particles out of eyes and nose.
    A hair forms at the bottom of a tiny sac called a hair follicle.
    Nails protect
    The tips of your fingers and toes.
    A nail grows from living cells in the nail rootat the base of the nail.
  • 7. Skin Injuries
    Skin is often damaged, but fortunately can repair itself.
    However, damage to the genetic material in skin cells can cause skin cancer.
