Respiratory System
Each day we breathe about 20,000 times. All
of this breathing couldn't happen without
help from the respiratory system, which
includes the nose, throat, voice box,
windpipe, and lungs. With each breath, you
take in air through your nostrils and mouth,
and your lungs fill up and empty out. As air
is inhaled, the mucous membranes of the
nose and mouth warm and humidify the air.
