Mucus
slimy secretion that
helps to warm,
moisten, and filter

that line the nostrils
and help to filter
air.

by the digestive and
respiratory
systems.

Bronchial tree
term describing how
branches of the
bronchi
get
continually smaller,
like a tree branch.
Lower Respiratory System
Bronchioles

of
the bronchial
tree.

Lungs
paired organs containing
bronchi that are
divided into
clearly
defined lobes.
Lungs
Lower Respiratory System
Diaphragm
