»Skin
Make your wager and hand it to the
teacher
Final Question
• Name three functions of the skin and explain
how it performs the function.
• Mechanical Damage - It makes a physical barrier.
Outer layers has cells that contain keratin, which
toughens the cells and has pressure receptors,
which alert the body of potential damage
• Chemical Damage - Once again the keratinized
cells block chemicals and pain receptors alert the
body
• Bacterial Damage - Block the bacteria, but also
the skin’s secretion are acidic (inhibit growth) and
skin cells have phagocytes (eat the bacteria)
• Ultraviolet Radiation - Contains melanin that offers
protection from UV damage
• Thermal Damage - Contains hot, cold, and pain
receptors that alert the body
• Desiccation (Drying Out) - Contains waterproofing
glycolipid and keratin
• Aids in heat loss (activates sweat glands and
allows blood to flow closer to surface) and heat
retention (stops blood from rushing to surface)
• Aids in excretion of urea and uric acid (makes up
some of your sweat)
• Synthesizes vitamin D (uses sunlight to convert
some cholesterol molecules to vitamin D)
Final Final Question
• Why would it not be wise to only have hair as
evidence if you were trying to prosecute a
defendant in court?
Answer
• Hairs within a species can have similar
qualities. Therefore, different people can
have similar hairs. Also, hairs vary from
hair to hair on the same person, so one
can never definitively say if a hair came for
a certain person; all that can be said is it is
similar to the person’s hair.
