Sagot :

Popmarsid
main stem= trachea or windpipe
two large branching stem= bronchi
little stems= bronchioles
individual grapes= alvioli or airsacs

INTERNAL RESPIRATION:
-Air from the bronchi travels to the bronchioles then to the tiny air sacs(alveoli) which connect to the lung capillaries.

THEREFORE: the bunch of grapes represents the alveoli.
