responsible for voice sounds
small, flexible membranes that
vibrate when air passes through
passage of air to bronchi
cartilaginous rings for protection
bronchus
passage of air to lungs
branching increases surface
area and mucus filters foreign
particles

passage from bronchus to each many branched tubes to
alveolus

nasal passages
oral cavity
larynx
trachea
alveoli
diaphragm
gas exchange
membranes are one cell thick
and surrounded by capillaries
for efficient diffusion
increase and decrease volume
of chest cavity
very thin, muscular structure
