Being human
Although we look different from
animals, our bodies are similar
on the inside. Our closest
animal relatives are
chimpanzees.
Water, water
Your body is mostly
water – it makes up
about two-thirds of
your weight.
No substitute
The human body is too
complicated for robots to
copy. Robots can copy the
way we walk, but they
can’t think or feel like we do.

The ingredients
Your body is made of just
a few simple chemicals,
plus water.
Carbon
is what diamonds
and coal are made of.
A fifth of you is carbon.
Iron
makes your blood
red. You have enough to
make one small iron nail.
Phosphorus
is in the
tips of matches, as well
as your bones and teeth.
Sodium
and
chlorine
make salt. Blood is one-
third as salty as sea water.
Potassium
is used in
some types of soap. It’s
also in your body fluids.
Nitrogen
is important in
muscles. It’s also the main
ingredient in air.
