SUBJECT: Your thyroid gland
is found just below your voice
box or larynx.
It wraps around your windpipe
or your trachea.
Your thyroid affects
your metabolism.
It makes hormones that affect
how fast your whole body works
and how it uses energy.
Your body uses thyroid hormone
to increase your energy
and raise your body temperature
when needed.
For example, that helps replace
the heat your body loses when
exposed to cold weather.
