Objectives:
1. Identify the key parts of the breathing system.
2. Describe the function of each part of the breathing system.
Materials:
Illustration (refer below)
Раper
Pen
Procedure:
1. Consider the bunch of grapes as the human breathing system.
2. Study the illustration of the breathing system: the main stem as the trachea,
the two branching stems as the bronchi, and all the little stems as
the bronchioles, and the individual grapes as the air sacs or
alveoli.
TRACHEA
BRONCHI
BRONCHIOLES
ALVEOLI
Figure 1. The bunch of grapes model of the breathing system
3. Trace the pathway of oxygen using the "Bunch of Grapes "model. Note
that air moves from the nose (nasal cavity), and mouth (oral cavity) to the
trachea, bronchi, bronchioles, and then into the alveoli (air sacs). The
air we breathe carries the gas oxygen. When we breathe, the
goes to the lungs.
