skin contains keratin
skin creates a barrier which is

well against almost all
pathogens
epidermal cells lack the capacity
to produce antibodies
the upper layers of the skin are
avascular
phagocytes reside in the loose
connective tissue of the dermis

would be able to fight off?

they have ineffective B cells
the HIV virus transforms
normal cells into cancer cells
the virus particles enter
macrophages in large
numbers
cytotoxic T cells are
ineffective because the
helper T cells are inactivated
by HIV
fewer B cells are produced

Artificial joints are constructed of stainless

unlike organ transplants, there are

steel and plastic do not degrade into
pieces small enough to enter a

the body recognizes the atoms as
self
steel and plastic have no antigenic
molecules
stainless steel knee joints are
eventually rejected, but at a slower
rate than transplanted organs

You have a cold; what's the best way to
prevent spreading it to others?

get lots of rest to keep the virus
from multiplying
take antibiotics to damage the
viral cell walls
wash your hands after blowing
your nose to reduce the spread
of viral particles
take large doses of vitamin C to
